I am attempting to migrate TFS 2013 team project to visual studio online using OpsHub visual studio online migration utility. When I get to the step where I have to select the team foundation server users to migrate it appears that my companies entire active directory is being loaded (over 38,000 users!). I really only want to migrate about 25 users, but it is telling me that I must migrate every users. As a note, when I create a new work item in TFS 2013, only 25 users are displayed in the drop down.
I am sure that there is some group that needs to be configured for TFS but I am not sure what exactly I need to do to get this list to only include the few people I need to migrate.
Edit:
I noticed in my DefaultCollection Windows Group section that we have a Dev-Contributors group with the exact people I want, but there is also a domain user group that contains my companies entire active directory. I am positive that dev-contributors is the only group we really need, is it advisable to somehow remove the domain users group?
Thanks for the help!
