I am trying to restore a .bak file (backup taken on SQL Server 2008 R2, compatibility level 100). I am restoring the backup on SQL Server 2012 edition. I get the below error. Unfortunately the original DB from where the DB was backed up is no longer available. Any suggestions on how I can restore the DB to 2012 ?
