Roll-backs may work fine for certain packages in isolation, but I wouldn't ever expect a large-scale roll-back of an entire distribution to leave you with anything other than a horribly broken system or one which, on the surface looks to be fine, but strange things keep surfacing as you discover it is more and more broken.
APT is just designed to avoid roll-backs as much as possible, and the packages that make up the Ubuntu and Debian, for that matter distribution aren't designed with smooth roll-backs as a design goal. Unless you have whole-system backups that are reliable, what you really need to do is ensure your entire home directory is backed up and possibly also on a separate partition , re-install from the CD image of your chosen version, and start restoring your data from your home folder s.
You may even need to selectively restore the dotfiles in your home directory in case any which have become accustomed to the new version don't quite work well with the older version. Before you do, you may want to peruse your installed packages and write down which ones you rely on, so you can re-install them. Don't forget backup first: your home directory any anywhere else you may have personal data. To put it simply: no there's not. These are the dangers of upgrading to testing releases!

There's a saying in my language which can be roughly translated as "You can't turn mince back into meat by rotating the mincer's handle in the opposite direction" : The upgrade procedure is one-way - while installing new versions of software, your configuration files and settings are modified by packages' post-install scripts to use new format which is required by new software.
Improve this answer. Sergey Sergey I disagree, upgrading a system is about replacing old packages with new packages, which should be a reversible process replace new packages with old ones. There's no inherent need to destroy anything during an upgrade, it's just that most systems we use don't really care about downgrading and don't support it well. However, there's no such tool, so my answer stands for the real-life Ubuntu and its upgrade tools.
Sergey : Nice one. Offtopic, which wise language is that? Show 1 more comment. If you want to test things in the future and you fear you might have issues, always make sure you do the following: Test the LiveCD first.
