We're running a German TFS 2013.4 on premise and want to move to Visual Studio Online. The OpsHub migration tool stops with a template mismatch.
I ran the TeamProjectManager tool (https://teamprojectmanager.codeplex.com/) and compared our template to the VSO template. The fields are there, but their names are different, one is German and one is English ("Fehler" vs "bug").
Would it be possible to convert our local TFS to English? It's a single-machine installation running in a VM, so we can take a snapshot and just try it. We don't have any customizations, but TFS was upgraded several times, all the way back from TFS 2008. I read somewhere that might leave behind some obsolete fields, which can also cause problems.
