I am running Yosemite on a 2010 MacPro.
I have a number of programs whose last OS was Snow Leopard, so I frequently boot into SL to run them. I'd read that I can run Snow Leopard Server in a virtual machine, but when I loaded SLS into a VirtualBox machine, it did not allow for a migration assistant import from the original drive. In fact, it could only see its own (virtual) drive, and nothing else. The question - Will Parallels have the same issue? Or is there another way to run both OSes on one computer, with no reboot, that I'm not seeing?
