Moving Symantec Endpoint Protection Manager from one server to another server

Hello,

I am testing the move of a SEP Manager running on a Windows Server 2003 R2 that is using a separate SQL Server database for SEP to a Windows Server 2008 R2 server using the steps described at http://www.symantec.com/business/support/index?page=content&id=TECH160736

As I am using a external SQL Server, do I need to restore the database that I've backed up on the previous steps? Because when I reinstalled the SEP Manager in the other server using the recovery file, I've connected to se SQL Server that I was using alongside the old SEP Manager server and the wizard told me that there was data on that database and asked if it should keep those or cleanup the database.

Thanks!
