I need to move, or copy, a TFVC (Team Foundation Version Control) repository from one instance of VSTS (e.g.: source.visualstudio.com) to another instance of VSTS (e.g.: destination.visualstudio.com).
I thought this would fairly straightforward, but I can only find information in regards to TFS (Team Foundation Server), not VSTS (Visual Studio Team Services). Or samples that convert to a Git repository, while I need to go from TFVC to TFVC.
I am not interested in migrating Work Items at this time, just the source code and its history.
No built-in tool to do it, there is a similar user voice: make it possible to move a Team Project between Team Project Collections
Regarding 3rd tool, you can try it with OpsHub Visual Studio Online Migration Utility.
On the other hand, you may change account owner of VSTS if just need to change owner.
