I came to know that name has changed when I tried to shrink the file. Here is the error message I got:
Shrink failed for LogFile "Tfs_TESTTFS_Log'. (Microsoft.SqlServer.Smo)
Additonal information
An exception occured while executing a Transact-SQL statement or batch.
(Microsoft.SqlServer.COnnectionInfo)
Could not locate file 'Tfs_TESTTFS_Log' for database 'Tfs_TESTTFS' in sys.database_files. The file
either does not exist, or was dropped. (Microsoft Sql Server, Error: 8995)
This is test environment upgrade and I checked on production environment which is still on SQL 2008R2, shrink works fine.
Please help.
