I want to use SQL Server 2008, but I'd also like to maintain a fall back position of switching back to SQL Server 2005. I know I cannot backup 2008 to restore 2005 and detach/attach won't work - what are my options?
[Update] To those asking why, two reasons -- one to develop from, where I can have access to 2008 features, but if a problem comes up or I don't find them useful enough, I can put my app back on 2005 and two, for run time so that if I find late in the game an unexpected problem.
