Hi Herman,
I have Labed this up in a virtual environment. After investigation I did find it is possible. Firstly I had to make the Dell badged CPPM VM the correct version to import the backup of our production CPPM. Import was successful. I will now attempt to upgrade the VM to the latest version of CPPM and then do a backup. Once that is done, I will runup a Aruba badged CPPM Virtual machine and see if I can import the backup. I will let you know how I go.
