Clone WP Multisite pointing to old domain during login and wp-admin

Hey guys,

I have a WP Multisite on testdomain.com and want to migrate it to my live domain livedomain.com. I have made the changes in htaccess, wp-config and database but it’s still pointing to the old domain when I am trying to login or wp-admin. Am I missing something?

Is there a way to search for and replace in the database the old domain? Or should I – in this case- use BackupBuddy? I want the testdomain.com stay active as this is where I am debugging and testing my sites.
