I'd recommend that this be handled the same as any other version
upgrade (eg etch->lenny)
1) First make sure that stable is up to date with all the latest updates.
2) Change sources as indicated above
3) Update your upgrade tools
# aptitude install apt dpkg aptitude
4) perform a safe upgrade first.
# aptitude safe-upgrade
5) Finish with a full upgrade
# aptitude full-upgrade
