Can one downgrade from 6 to 5 again?

I bought Desktop 5 a couple of months ago - got it running, mostly pretty smooth. Then it upgraded to 6 for me, and things have been far less smooth. I had WinXP in a BootCamp partition, which is what I'm using with Parallels - and it worked pretty well with 5, but it keeps "loosing" the partition and naming a new one on me.

Anyone else facing the same issue?

 

Similar story, but using Windows 7. used Parallels Desktop V5 fine for a couple months. Upgraded to V6, and have not been able to start my Windows 7 VM yet: I get a 'fatal error' message. Mac still runs fine, but no Windows. Have started trouble ticket with Parallels, do I uninstall and reinstall V6? uninstall and reinstall V5? parallels is a cool tool!

 

Just read this horror story in another thread.

You need to decrypt the VM before downgrade it

Well what I did was to reinstall Parallels 5 without removing Parallels 6. Then started Parallels 5 to make sure it worked and then I trashed Parallels 6. It worked fine for me. The problem I was having with 6 was just performance....my entire machine slowed down to the point it was unusable.

 

I have the same problem with the performance.
In Parallels 6, when i switch between the VM and OSX, it was very slow.
I downgraded to version 5 and now I doesn't have problems with the performance.
