Hello
I have migrated my TFS2010 data into TFS2013. I have customized my work items in TFS2010. They are all working fine there even I will be able to change in them. But after migration, I am unable to save the work items after change in any field. After changing when I try to save the work item I got the following error.
"Workitem Type : Bug
The 'not' attribute is invalid - The Value" is invalid according to its datatype 'http://schemas.microsoft.com/visualstudio2008/workitemtracking/typelib:identityname' - the pattern constraint failed. there were validation errors. Continuing to save may cause the file to become unloadable, do you want to continue?"
If any know the solution of this problem, please write the proper solution so that I can resolve the issue.
Thanks.
