How to change the tenant region for Nintex Analytics if mistakenly choosing the wrong region during installation.
To be able to change the region you need to remove the Nintex Analytics farm properties using the below command:
$farm = Get-SPFarm
Perform an IIS reset and restart the SharePoint timer service after running the commands.
You should now be able to reactivate Nintex Analytics and reselect the region.
The above instruction is recommended for the scenario that there is no data connection being created on the previous tenant region.
