Use backup/restore...

I believe this will grow to be a personal preference. We often use the backup/restore method as it doesn't create any downtime. However, you do have to have the extra space on the server to create the backup file.

The detach/attach method will be faster because you don't have to worry about the time to take a backup. In this case there will be downtime when you detach the database and copy the files over to the new server.

This will completely depend on your SLAs and your infrastructure. Just take a few minutes to test each scenario to see which one works best for you.

Thanks for the feedback. Yes we can afford few hours of downtime

So possibly the detach/attach is the way to go. I am going to

Try.

I would use the backup/restore method...less risky...no chance of the file not re-attaching.

restore database mydb

from disk = 'd:\data\backup\mydb.bak' with replace

will overwite database at destination server..

Typically I would just give the answer, however, I think this is a good learning opportunity. Just checkout the RESTORE DATABASE syntax and the REPLACE option.

Try something like the following:

Use Master

Alter Database zReports

SET SINGLE_USER With ROLLBACK IMMEDIATE

RESTORE DATABASE mydb FROM DISK = 'x:\backup\mydb.bak'

WITH REPLACE

GO
