We are currently upgrading our team foundation server from 2008 to 2012 and have come across following issues:
There are staff on leave who have changes checked out to them. If we do, force undo checkout on their changes, what actually happens? Do they lose their changes?
What if we don't force undo checkout and bring everything across as it is, Can they just rebind their file to the new TFS and then checkin their changes?
Is there a way to do a force check-in? if yes then how?
