I find this very surprising, that one can restore a DB created on an Enterprise server onto a Standard server, even if both are at the exact same version and service pack.
I wondered about the usage of features that are Enterprise only.
I found this in Brent Ozar's 60-Minute Blitz script:
Are any of the databases using features that are Enterprise Edition only?
If a database is using something like partitioning, compression, or
Transparent Data Encryption, then I won't be able to restore it onto a
Standard Edition server.
EXEC dbo.sp_MSforeachdb 'SELECT ''[?]'' AS DatabaseName, * FROM [?].sys.dm_db_persisted_sku_features'
I have to go find a copy of the SQL Server 2008 standard edition and test it.
