SharePoint 2013: Cannot complete the copy or merge operation because the databaseschema versions are different

You may use Move-SPSite in SharePoint PowerShell to move site collections from one content database to another. However after applying updates and creating new content databases, when attempting to move a site collection, you may receive the following error:

Cannot complete the copy or merge operation because the database schema versions are different.

Sometimes you content databases do not get properly upgraded during the installation of a cumulative update or service pack. There is a quick an easy fix. Just use the Upgrade-SPContentDatabase cmdlet to update the content database:

Upgrade-SPContentDatabase -Identity <<content database name>>

Just for good measure, I usually run this cmdlet on all content databases - just in case. The system will let you know if the content database does not need to upgraded.

Once all databases are in sync, you may use the Move-SPSite as normal without any database schema errors!
