• I may have confused some of you:

    I want to upgrade SQL Server 2000 instances. Their OS is Windows Server 2003 SP1. The instances have no SQL Server service pack or SP3.

    Microsoft does not support anything less than SQL Server SP4 when upgrading to SQL Server 2008.

    It was also my understanding that the OS on the SQL Server 2000 instances must be Windows Server 2003 SP2 before attempting to upgrade to SQL Server 2008. Is this correct?

    Once this is complete, I want to copy their .bak files to the new SQL Server 2008 instance. That instance has Windows Server 2008 SP2.

    Before copying the files over I will use the upgrade advisor. That's it. Sorry for the confusion...
