history. sp_delete_backuphistory

Cleanup Mail History sysmail_delete_mailitems_sp sysmail_delete_log_sp

Maintenance Considerations When Upgrading a Database

Change Database Compatibility Level ALTER DATABASE [DatabaseName]

SET COMPATIBILITY_LEVEL = 100

Check the integrity of the objects in your database DBCC CHECKDB ([DatabaseName]) WITH DATA_PURITY

Correct Row and Page Counts DBCC UPDATEUSAGE ([DatabaseName])

Set the page verification method to CHECKSUM ALTER DATABASE [DatabaseName]

SET PAGE_VERIFY CHECKSUM WITH NO_WAIT

Update Statistics With Full Scan sp_msforeachtable 'UPDATE STATISTICS ? WITH FULLSCAN'
