Detach and Offline for moving databases
02 February,2015 by Tom Collins
Detach or Offline : Which is better?
Some SQL Server DBA use offline , others Detach in moving databases. I use either , depending on the situation.
If replication is involved I use the Offline method. Others I use Detach\Attach.
Be mindful that both methods will attempt to close the database cleanly , and close the handles. And if using the Detach method – the file ACLs can be changed
Detaching removes the SQL Server registration of the database . One of the consequences is locations will need to be stated when reattaching.
The offline method leaves the registration unaffected, resetting to Online – allows operations to continue.
