Which would be a shame given how well Parallel works on Catalina. There is also the pro version for 199. VMware Fusion 12 Player costs one payment of 149.00.

At least that is going to be usable for more than 12 months and will support more than a single major release of macOS. Although it is slightly more expensive than the Parallels subscription fee, once you have the license, it is yours forever. If v15 is not going to work on Big Sur I am definitely going to abandon Parallels again and purchase a VMware Fusion Pro license. I have just recently purchased a license and am definitely not interested in a) a yearly software subscription, or b) yearly mandatory paid upgrades because they refuse to support their software for more than 12 months or more than one major macOS release. Parallels or VMWare Fusion are nicer for Microsoft Windows and are basically a toss-up. We take a comprehensive look at both, and compare how they perform to each other, and to the free VirtualBox, with benchmarks examining overall processing power, graphics performance, and real-world tests like battery life and video encoding. I really hope that Parallels is going to continue supporting v15 on Big Sur. With the recent launch of Parallels 10 and Fusion 7, consumers are once again left wondering which virtualization platform to choose for their Mac. Microsoft has a fairly extensive algorithm to determine when a re-activation is required.

It probably depends on the amount and extent of virtual hardware changes. However, when I first migrated a Windows 10 VM von VirtualBox to Parallels on my iMac it did. As far as Windows 10 is concerned, I can play Mass Effect 1, 2 and 3 with 60 frames per sec on 1080P, all settings high. I'm not even sure what it measures, on my MacBook Air 16GB M1 it gives 60 on the internal monitor, both for MacOS and Parallels (57-60).

I migrated two VMs from VirtualBox to Fusion (1x Windows 7, 1x Windows 10) on my MacBook, which did not trigger Activation. First of all that is a completely outdated (2017) test.
