I am running parallels 12, and will be upgrading one computer to parallels 15. Will the existing .pvm need to be upgraded to work with 15, and if so will the upgraded .pvm be compatible with 12? I would prefer to not need to double the storage space needed, and would also prefer to maintain only one vm/image.
Hi, all your .pvm will work with Parallels Desktop 15. But we recommend to make a backup copy of your VM before the upgrade. Please let us know if you have any additional questions.
