Can I directly upgrade WSS 2.0 to WSS 3.0 SP3. I have run the preupgrade and there are no issues with upgrading.

Take backups just in case as the direct in-site upgrade doesn't allow any going back if things go wrong. But I see no reason (and have read nothing) why an upgrade to the SP3 version of WSS 3.0 shouldn't work just as an upgrade with the original WSS 3.0 worked.2010 Books: SPF 2010; SPS 2010; SPD 2010; InfoPath 2010; Workflow etc. 2007 Books: WSS 3.0; MOSS 2007; SPD 2007; InfoPath 2007; PerformancePoint; SSRS; Workflow Both lists also include books in French; German; Spanish with even more languages in the 2007 list.
