How to change the domain only without migrating the files - wordpress

I have two business domains, for example, domain.com and dev.domain.com.
Since I had to keep the old website for running the business while developing website, I keep the old website to domain.com and bought the new theme, installed, and developed in dev.domain.com.
After finished the development, I wanted to use the domain.com instead of dev.domain.com, but when I migrate all the file, all the plug-ins were not working because of license reason.
Since I don't want to develop entire website again, I just made domain.com to forwarding to dev.domain.com.
Is there way I can change domain to domain.com?
Thanks,

Not entirely sure but you're probably getting errors because WordPress saves the site URL in the database so after you move the files to domain.com, the database is still requesting stuff from dev.domain.com. Changing the one table in the database (site_url under wp_options) is sometimes enough but if you've been developing a site I'm guessing you've got a bunch of links and images set up with the dev.domain.com URL. What I usually do when migrating a dev site to live is...
Set up a new Database and User/Pass for the new live site.
Export the database from the dev site.
Open the database in Notepad++
Use Find and Replace (ctr+h) to find dev.domain.com and replace with
domain.com, choosing Replace All.
Now import this database to the new database you set up earlier, and
change the wp-config.php database settings to the new database.
Be sure to keep copies of the backup before you edit the database in case anything goes wrong, but you should be good. This is how I do it all the time.

This https://interconnectit.com/products/search-and-replace-for-wordpress-databases/ is probably a better method than trying to load your entire db into a single text file is not the most viable option.

Wordpress wants to install itself, rather than run the blog

We have created a duplicate of our website on a new server as part of a migration. We have a wordpress blog that is part of our website.
The docroot of the wordpress site is set as an alias in our main site. The result is that to access the site home page, the following url is used: https://www.rephunter.net/blog/.
The new environment is not available to the public at this time, and is only accessible within our VPN. When the above link to the blog is followed, instead of the expected home page of our blog, we get the page at https://www.rephunter.net/blog/wp-admin/install.php, which wants to install a new site.
The configuration in the new environment is supposedly an exact copy of our production site from some time back. The permissions on the main files is the same.
What is it that is causing the attempted blog access to be redirected to the installation script?
EDIT:
The responses so far have not really absorbed the intent of the previous information. We are not migrating in the normal sense. Rather we are testing in a new virtual environment that will eventually lead to a more normal migration.
We have an exact duplicate of our original wordpress and database environment that is running in a virtual environment with an updated protocol stack that is only accessible if you are on the VPN for that environment. As far as we can tell, there is no difference in the configuration.
For example, the parameters in wp-config.php are exactly the same as in the original installation. When php runs, it sees the same environment, with host names and everything identical. It would not work otherwise.
Yet if there really were no difference, it would just run. But since WP is trying to install a new database, there is something different that we are missing.
To further illustrate this: supposed you took an image backup of the wordpress installation and the database, and put it in a different VM, and set up the DNS and everything as it needs to be--the new environment looks no different than the old one. All databases, wp-config settings, etc, are the same. So our main website and database functions very similarly.
As I mentioned above, the difference in the protocol stack should be considered. The old system is on PHP 5.6.27--the new one is on 7.3.4. So that could be causing some difference, which maybe somebody might recognize. Wordpress is 5.2.2 and should be compatible with both PHP levels.
We believe there is some relatively simple parameter setting that we are missing. For example, as in the first answer that $table_prefix is set wrongly. But that is not it in this case.
WordPress redirects you to that installation screen because the database it's connecting to is working (meaning, the username and password are correct), but the data it's expecting to be there isn't. Therefore, it assumes it's a new / empty database and prompts you to install WordPress.
I've seen this happen in two scenarios:
The database really is empty, and thus WP needs to install the standard tables and info
The table prefix in your wp-config.php file is incorrect for an existing database
Look at your wp-config.php file in the root directory of WordPress, and look for a line similar to this:
$table_prefix = 'wp_';
Then, open up the database (phpMyAdmin or some other interface to browse what the database structure actually is) and confirm that the table prefixes (the first few characters of the table names) actually match what's set above.
Hopefully this gives you something to go on! Let us know what you find
Migrating Wordpress websites can be quite tricky. I've worked as a WP developer for a number of years and always struggled with manually migrating websites.
There are a number of factors to consider:
WP stores a lot of installation specific information within the database. So you can't do a database dump and upload the export into a new database.
Changing the website url within the wp_options table in the databased there are still other references to the original url scattered throughout the db.
You could try a find and replace all using an editor that supports this sort of functionality (vscode, sublime, atom) but things always end up breaking and your doing tons of "find & replace" actions.
I have always relied on a 3rd party tool Backup Buddy as it simplifies the entire backup and migration process and offers the peace of mind of having easily deployable backups for your website.
Backup Buddy allows you to export your website as a zip and then you can move the zip to any server you want and the plugin provides an installer script (php) to guide you through the migration of your wp site to any host and database of your choosing.
Note: I am not in any way affiliated with iThemes or Backup buddy, and I do not stand to benefit in anyway if you decide to use the plugin. This is only advice on a tool that I have found helpful, reliable, have had success with, and currently actively use on a number of websites that I maintain.
WordPress display installation page because you have not update your wp-config.php file after migrating server so please follow below steps in future when you migrate your website.
Please follow this steps when you migrate your WordPress website from one server to another server.
Back up your website files/database
Export wordpress database.
Create database on your new host server.
Edit the wp-config.php File and edit this details.
Add new database name
Add new database username
Add new database user Password
Add new host as per your hosting provider or (localhost is default)
Import your database to new server.
upload the WordPress files to your new host
defining new domain URL & Search/Replace old domain URL

What step have i missed? Transferring wordpress site

So i have recently tried to transfer my wordpress site to another server.
I have followed a few guides, but i definately seem to be missing a step.
Basically what i have done is:
export original database (phpMyAdmin)
Save all relevant files (ftp)
install fresh wordpress on new server. (wp backend)
'drop' all table fields in new wordpress (phpMyAdmin)
import original database to new location (phpMyAdmin)
transfer theme, plugins, uploads. (ftp)
activate theme, plugins. (wp backend)
update permalinks. (wp backend)
The problem is, i am left with a default looking wordpress installation, and not my orginal page-home.php and corresponding css.
Also, if i go to wordpress backend SETTINGS > READING > Frontpage:static; i only have the option of 'about', not home, i should have 'home'...
Sorry if i am vague, let me know if any screenshots are required.
We really need a little more info like:
when you say plain, do you mean just the theme is not set and you're on the default theme, or there is no theme, or do you mean even your content is not there?
the site you removed it from, where was the installation located? Was is in the public_html folder or a subfolder of that? Did you put it in the same place, ie not inadvertently put it in a different folder
(I've actually typed the bulk of the post and come back to the top for this one, but):
Are you sure you're checking the right site?
Have you kept the same domain name?
Has the domain name propagated to the new server?
Is the CSS being loaded from the correct domain (has anything been hardcoded to the old server)
Let's go through a few broader options:
1. Check how many WordPress installs are on your domain
First off, it sounds like you may have two WordPress installations. If you have the backend setup correctly with your themes but you're seeing a plain site, it sounds like you're looking at another install. I'm not saying you do have multiple installs, but it is a place to start looking.
A question to ask yourself here is: In this plain looking site, do you see your content, or the content of a default site? If you see your content, you may jump ahead to section 2.
If you're saying there is a home page but you're not seeing it as available under static pages, either:
You're looking at another site (but there should be a home page* even in a default setup—from memory), or
You're Home Page title may have changed, or have become "unpublished", ie reverted to a draft, or pending review. Check the page:
actually exists,
has the title you're looking for
the slug hasn't changed
(*note: although it could be a Welcome Page I'm thinking of here.)
Double check the database
The easiest way to do this is to go into your database and see how many WP databases there are. Check each database and look for the underlying table structure, it sounds like you should be able to identify it pretty easily. If it's not a multisite install, the table prefixes should be wp_ unless you changed them somewhere.
While you're playing around in the database, Take note of the database name and table prefix.
Double check the folder structure
Have a look for a second instance of your folder structure, maybe you dropped it into the wrong place).
2. Check the WordPress installation is actually connected to the database
Check the WordPress configuration file wp-config.php is connected to the database. Check wp-config.php sample from codex, you'll want to see the correct database name and table prefix in there.
From here you should also check the username has been setup correctly and is as you expect it. Remember, the database name will likely have a different prefix between hosting providers, unless you've managed to keep the same login name with each provider. ie, I'm talking about the database prefix here, not the table prefix.
(another note: most database connection issues will result in errors appearing on the page in lieu of your site, which leads me to believe it's at least partially setup correctly.)
TEST: What you can do is rename the old wp-config.php to something else and don't create a new one, then visit the website and it will lead you into setting it up again where you can enter the database details (your site info will still be intact, this will only reset your config file, not the database, although it could reset the connection between the filesystem and database).
3. Domain name propagation and DNS settings with your new host
As I mentioned previously, are you checking the right server? Are you sure the domain name has been propagated (if you're using the same domain name that is).
Check the IP address with your DNS provider (for your domain name) is correctly pointed to your new server
Then check that from your command line by typing ping {your-domain-name} and see that your IP address comes up
Check the DNS settings with your web host are setup correctly and that your domain name points to where you want it to point to (ie, public_html or the relevant subdirectory there-of). (This resally does come back to point one, which if you covered it, this shouldn't be an issue
Check that you dropped the files (and all the files) into the correct physical directory, ie public_html (or sub-dir)
If none of these help, please leave a comment with any further developments you've made and as much info as possible, and we can start looking in other areas.
*notes about the database name:
when playing with WordPress directly, ie in the configuration files or the backend administration settings, the database will include your {username}[underscore or hyphen]{database-name}
when playing in phpMyAdmin, they will already be included and you will just provide the {database-name}.
Fellow this steps
export your sql from cpanel---phpmyadmin
make zip of your files in cpanel
import the file in new domain and extract it
create a database link to the new domain
go to new database which you have reacted through phpmyadmin--delete all the tables which was installed by wordpress.
import that sql file which you have downloaded from old website
and in phpmyadmin change the url to new domain name
Regards
Follow these steps:
export database from phpmyadmin.
zip your WordPress project via c-panel.
upload zip file on new domain via c-panel.
extract zip file.
create new database and import old database in new phpmyadmin.
configure user name and password and database name.
change url in database table. from wp_operation table home_url and site_url

moving WordPress over to domain, after working on it locally through MAMP

I've finished the styling changes on WordPress and I'm ready to move it from MAMP to my domain.
Will this involve any changes to the WordPress files or can I just drag it over to my new domain once I purchased it?
The main start you must make is update your wp-config.php
define('WP_HOME','http://www.mynewdomain.com');
define('WP_SITEURL','http://www.mynewdomain.com');
That way wordpress knows what domain it MUST run from.
The reason you do that is because without this you may not be able to access admin, login, etc etc.
When this is working and you have logged in, go to wp-admin and go to your permalink settings.
Make a NOTE of your settings, then change them to default (and woocommerce settings etc).
Go to your home page and a few others, and notice how messed up your urls look :)
Now go back to permalink settings and restore them (the point of this is to make sure your .htaccess file that wordpress depends upon is set correctly)
Finally, have a look at https://github.com/veloper/WordPress-Domain-Changer to change your sql etc if needed.
note this method is very handy for developers so you just update your wp-config.php for localhost or development or production (not for testing purposes, don't use your local pc. copy it all up to a subdirectory of your hosting partner e.g. http://www.mynewdomain.com/mytestarea. Make sure you use a COPY of the mysql database (never point both to the same database). You now can test on the hosting platform without disturbing the live site or your development causing issues to other people.
It's been a long while for me personally, but you'll want to change the SiteURL via the options menu in wp-admin.
Otherwise, just make sure your MySQL database is exported over, your credentials and user permissions are all setup and those work too.
If you still have problems:
https://codex.wordpress.org/Changing_The_Site_URL
https://codex.wordpress.org/Moving_WordPress
The database has to be updated. What always works for me is that I export the database from phpMyAdmin or MySQL (using mysqldump) and open the exported .sql-file with a text editor, like Sublime Text.
Now you want to find any occurence of your previous URL. Let's say on your dev machine the URL to the index of your Wordpress site is http://localhost:8080/wordpress and you want it to be on a website under https://domain.com you simply do a Find & Replace using that and replace everything with https://domain.com.
For older Wordpress versions you have to update the .htaccess files if you have custom URL's.
You have to make a search replace in your database and replace your local domain ( test.lo ) with the live domain ( test.com ).
To do this you can use the script from here: https://interconnectit.com/products/search-and-replace-for-wordpress-databases/
Add the searchreplacedb2.php file in your route folder and the access test.lo/searchreplacedb2.php and follow the steps there. This will replace your local domain with your live one everywhere in the database.
You can't make a simple search-replace because the local domain might be serialized in some fields in the database, and a simple search-replace will not replace those.

How to push wordpress from mamp into hostgator

I have done a blog in mamp and would like to push into hostgator. Must i recreate everything in hostgator like Installing Wordpress on Hostgator. Is there any way i could just push my stuff straight into hostgator without redoing everything in hostgator. Need some suggestion.. Thanks..
It's quite easy to deploy a local version of Wordpress to a live server. First of all, you are right, I would not bother installing a clean copy of Wordpress on your server, you'd then have to totally rebuild the site.
What you need to do is;
FTP all your files from your local machine to the server.
Transfer the whole database from local phpmyadmin to a new database on the server
Change the database connection details in wp-config.php
Make any necessary changes to your default Wordpress .htaccess. What I mean here is that your MAMP site probably isn't in the root but your live site probably will be. If you have SEO permalinks set up then you would remove the Mamp subdirectory from the rewrite rule and the base in the .htaccess. Your host might also require you to add rules here (ie specifying which version of PHP to use etc). You could always install Wordpress using their installer to see if they add any special rules themselves.
All easy so far - now comes my tip. Moving Wordpress databases from your local development environment to live can be a massive pain because Wordpress (and lots of plugin/theme developers) use serialized arrays to store data. So if you do a find-and-replace on the database to replace your old url with the new one, you will disable lots of things like config settings and widgets (text widgets specifically, but there's loads of stuff you end up having to recreate).
Download this file;
http://interconnectit.com/124/search-and-replace-for-wordpress-databases/
and upload it to the server and access it directly in your browser. Run through the quick form and perform a serialized array-friendly find and replace on your database urls. Job done. Good luck.

Moving Wordpress with Headway to a new domain breaks the site

I have a client's wordpress site that is built using Wordpress and Headway. I need to move it to a new domain on a new shared server ( same host provider with the same hardware configuration ).
I've moved many wordpress setups like this before, including Wordpress / Headway combos. I've also, during debug, used Headway's documentation and videos to double check that I'm doing everything correctly.
I moved the database over and replaced all occurrences of the old domain with the new domain, and updated all filepaths. Then I copied the public_html folder to the new server. The site should be working at this point.
Instead I get the Headway error message No Content to Display on an otherwise empty html page. I've traced the problem to the wp-config table where Headway stores serialized data for it's blocks. I can update data throughout the database to the new domain everywhere except in these Headway entries in the wp-config table. As soon as I update those, the site starts to fall apart all over the place, and if I update them all, the site loads the Headway error message No Content to Display. The underlying Wordpress system seems to still be working as I can load the /wp-admin console and all my content exists and looks correct.
If I trace the problem deeper, it appears that the Wordpress function get_options() is failing in the Headway file data-layout-options.php. I have been unable to debug any further.
The site works perfectly on the original domain, and, in theory, I'm doing a direct copy of all data and then simply replacing the old domain with the new domain.
Can anyone help with a similar problem? It feels like I'm chasing a bug in the code when really it's some sort of simple oversight or config setting that has been munged. Please help!!!
I was indeed close to the problem.
The serialized Headway data in the Wordpress wp-config table contains string lengths. Migrating the database oneself, and then grepping and replacing the old domain with the new domain and old web folder file path with the new web folder file path causes unserialization to fail in the Wordpress system ( eg. the get_options() Wordpress function ).
Instead of writing a custom script to deal with the string lengths, I tested a few database migration plugins. WP Migrate DB was the winner and solved the problem.
Migrating the Database
Install the plugin on the original domain ( original Wordpress install ). It will ask you to input the new domain and the new file path of your web directory ( the web directory file path is very important as well ). In my case, for example, the file path of the web directory had changed from /home2/old_username to /home6/new_username.
The plugin will then dump the entire Wordpress Database and replace all occurances of the old domain and old file path with the new domain and file path of the web directory. The .sql dump will then save locally on your computer.
This was not perfect however, and I still needed to do a few of my own grep and replaces. Additionally, I had to be careful about this because a few of the ones that were missed were in the Headway serialized data and I had to do MySQL queries to make sure I updated the string length properly.
These few updates were missed because some of the database entries had http://www.olddomain.com and some had http://olddomain.com. The plugin did not catch it all, but made it manageable to replace by hand.
Finally, I had to import this updated .sql dump into an empty Wordpress database on the new domain.
Moral of the story is that Headway V3 is not simple to migrate to a new domain. You must be very meticulous.
Another option, that I did not try because it costs >$75 was BackupBuddy. It's likely that BackupBuddy will still miss some domain and file path updates, so be careful.
I have found the solution of T. Brian Jones and have just applied it for WordPress 3.8.1 with HEADWAY 3.6.2.
All works fine.
One trick for newbes like me: if you don't know the file path on the server where you are moving your database, before you do database dump install WP Migrate DB on this server, run the plugin (Tools) and get the path from there...
Thank's TBJ
