I agree, after bringing the site down or into "under construction" use
database tools to copy the data, and don't delete those .sql files...
Also Be careful with access.gdbm you might want to keep that as is.  

Are you also upgrading software such as apache, perl, mysql/postgresql,
interchange, mail software?  If so, make sure you got all the needed
modules config files, etc.  Check your payment gateway specific stuff
just in case, also check email services, and also if there are any url
changes during this "upgrade", set up permanent redirects for all of
them to keep you up in the ranks.
