I'm starting to plan an upgrade to SQL Server 2008. Here is my current configuration: 2 Clustered Servers running Windows Server 2003 and SQL Server 2005. Want to upgrade Servers to Windows Server 2008 and SQL Server 2008... clustered. Special note: These are the ONLY 2 Servers I have... I can't shift the databases to another Server. That part scares the c**p out of me. I'm guessing the best way to do this is (after storing backups in a secure place) to wipe out both Servers and start from scratch. I've been given 24 hours of downtime... which I'm thinking is not near enough.
