ERROR: TF55030: Rename Data Tier failed. Please verify that the supplied Data Tier name is a valid Team Foundation Data Tier name, that the Data Tier can be accessed on the network and that you have administrative rights.
解决方案：
You have enough permission to run RenameDT command.
You must be a member of the Team Foundation Administrators group and a member of the sysadmin group on SQL Server. Please read “Required Permissions” section of the MSDN document RenameDT Command for more information.
You can connect to the new DT in AT machine.
You can open SQL Server Management Studio or create a .udl file on AT machine, verify you can connect to the new DT.
Reporting service works correctly.
