Making Template Changes to the Projects Migrated from Visual Studio Online

So, you have migrated TFS projects from Visual Studio Online and now you want to make certain improvements to newly migrated projects. Well, you're out of luck. When you try to customize work item types of the existing TFS projects migrated from the cloud, you will receive an error. Even though you have all the necessary permissions. So, what exactly is the problem here?!? Apparently, there is something in the migration process that causes certain metadata missing from security tables when TFS contents are moved from Visual Studio Online to the on-premises servers. As a result TFS simply does not know that you're now allowed to modify the project template.

To solve the problem, you will have to call Microsoft technical support. They will send you the fix. Hopefully, they will integrate that fix into the migration, so this kind of think does not happen. Hopefully…
