Last weekend, we had upgrade the TFS2010 version with TFS2012. all workitems, changesets and reports etc are upgraded sucessfully.
Now the issue is that, the workitem assigned To field contain the golbal directory user which are not proper. i.e. the correct name is Pravin.Pandit [ABC/XYZ/City] but now in TFS2012 is it looking like Pravin.Pandit ABC XYZ City
Is that any configuration was missedout in upgrade process or is any know issue in TFS12?
Addinal - TFS10 & 12 are in same domain. Old and new workitems creation shows same incorrect user name with respect to golbal directory.
