Resolve TFS Integration Platform Conflict - TFS WIT bypass-rule submission is enabled. However, the migration service account 'Chaminda Chandrasekara' is not in the Service Accounts Group on server

I have experienced the error below while trying to migrate work items from a TFS team Project to another team project using TFS Integration Tools.

  

Microsoft.TeamFoundation.Migration.Tfs2010WitAdapter.PermissionException: TFS WIT bypass-rule submission is enabled. However, the migration service account 'Chaminda Chandrasekara' is not in the Service Accounts Group on server 'http://tfsserver:8080/tfs/sandbox'.

The fix was so simple thanks to  Chev Bryan's blog post here.

I just executed below command in VS 2012 Developer Command Prompt to add the account executing migration to Team Foundation Service Accounts.

tfssecurity /g+ "Team Foundation Service Accounts" n:domain\username ALLOW /server:http://tfsserver:8080/tfs

Need "Edit Collection Level Information" to execute above command.

The migration was successful
