Glad to hear that VMware Importer works for you!
Did you have any issues with the virtual hardware changing from Parallels to Fusion, or does it run well?
How about the VMware Tools installation, especially for Solaris/Fedora?
I copied the appropriate tools over to the Unix virtual machines prior to importing and ran them manually. I saw that recommendation in a tip sheet or blog or perhaps another post here, can't recall. It went very well.
