Hi, I've an iMac running OS X 10.6.8 and Parallals 7... trying to update to El Capitan or Sierra. Would love to move the current VM of Windows 7 to what ever version of Parallels (13?) runs on El Cap or Sierra. Is this possible to do from Parallels 7? If so, what steps are required? Again, was hoping to move the existing VM over. Thanks in advance.
