Transitioning Parallels 7 to Fusion 6. Any tips?

I was running XP via Parallels 7 before I installed Mavericks. I decided to transition my VM software to Fusion 6 rather than upgrade to Parallels 9. What is the best way to transition? Just uninstall Parallels and install Fusion? Obviously I can't run XP (yet) to manage any of the Windows software I have installed, although it is only a few items, all of which I can simply reinstall. Still, I'd like this to be as clean as possible. I typically use AppCleaner 2.2.1 for my uninstallation needs.

Your thoughts are welcome, thanks.
