Your Windows VMs that run on your old Intel Mac will not work on an Apple Silicon Mac. Not under Fusion and not under Parallels. The only version of Windows that runs on Fusion is windows 11 and in particular the ARM version of Windows 11
There no silver bullet or magic tool that will “convert” what you have. You will need to build a new Windows 11 ARM VMs on the M2 Mac and migrate your data and applications to the new VM. You can not upgrade those VMs in-place because Microsoft does not provide a tool to “upgrade” a system running Intel Windows to ARM Windows.
Think along the lines of “what would you do if you had an old computer running Windows and now have a brand new computer that won’t run your old version of Windows?”
You would be looking at some things like copying your old data to a disk that you could attach to a new VM to more creative tactics such as attaching the virtual disks of the old VM to a new VM to copy data. You will need to make sure that your old applications run on windows 11 ARM and in some cases may need to upgrade or replace apps depending on what you find.
