Invoke Error updating Business Central to v20 - dynamics-business-central

Question

Trying to update to BC20 and I am getting an error at the Invoke-NAVApplicationDatabaseConversion command saying:
Invoke-NAVApplicationDatabaseConversion : A technical upgrade of database 'Demo Database BC (19-0)' on server
'LOCALHOST\BCDEMO' cannot be run, because the database�s application version '131112' is greater than or equal to the
platform version '131112'.
Does anyone know a fix for this or what I need to do?
Here is my whole script:
$OldBcServerInstance = "BC190"
Import-Module "C:\Program Files\Microsoft Dynamics 365 Business Central\190\Service\NavAdminTool.ps1"
Restart-NAVServerInstance -ServerInstance $OldBcServerInstance
$OldBcServerInstance = "BC190"

Answer 1

I believe you are getting the error because you are using the version 19 PowerShell Modules:
Import-Module "C:\Program Files\Microsoft Dynamics 365 Business Central\190\Service\NavAdminTool.ps1"
In order to do the technical upgrade from one version to another you must use the PowerShell Modules of the new version. Depending on your where you installed the new version it could be e.g.:
Import-Module "C:\Program Files\Microsoft Dynamics 365 Business Central\200\Service\NavAdminTool.ps1"
Note that the folder 190 has been changed to 200.
