Is it possible to rename a TFS2010 team project?
The project in question is based on the CMMI 5.0 team project template, but it has been modified with several custom modifications (new WITs and link types).
For a rename to be feasible, all history must be maintained.
In all: No, it can't be done.
Your only shot is to create a new Team Project named as you 'd like and then move everything to it. This involves serious work done by hand.
After that, you can't erase your old TeamProject - you will loose the history. You can lock it and make it unavailable to everybody.
After having done this a few times we think about the names of our Team Projects a lot. If at some point their name is(gets) wrong, I 'd say we 'll live with the mismatch.
