Backup Exec 10.1 -> 11 SQL Error

I got this error today:

The current version of Backup Exec is using an instance of SQL that is not compatible with Backup Exec 11d.
Please upgrade this version of SQL to a minimum of SQL Server 2000 Service Pack 3a or later before continuing with the upgrade.

the answer from symantec was:

remove 10 install 11 copy files from 10 to 11,

seemed like a lot of trouble,

this is what i did,

regmon setup.exe, saw it was looking for an instance that was not in the reg

renamed the database key: BEDatabase to BEDatabase_ (as i dont care about previous data really)

done
