Thanks, that's a great tip.
What happens if some of those packages aren't available at all under "testing"? Would the entire procedure fall on its face?

That's pretty much it. :-/
If you do end up going that route, here's something you can do to at least make it simple. On the machine in question, execute the following command:
dpkg --get-selections > packages.dpkg
Save the output file (packages.dpkg) to a floppy or remote location for future use. This file is a list of your installed packages, which should make your task simpler if you go the reinstall route. Once you've got the new base install and apt sources set up, don't run any other package installation programs yet. You can then pull up the packages.dpkg file and run the command:
dpkg --set-selections < packages.dpkg
This will tell the system which packages to install/uninstall en mass. Once that's done, run:
dselect install
That will install your selections automagically, asking you the necessary config questions. You should then have a clone of your previous packages, but from whichever branch you prefer.
