I am runinng Fusion 2.0.8 to run XP. I am thinking about upgrading my OS from Snow Leopard to Lion. That will require upgrading to Fusion 4.0. Can I upgrade seamlessly to 4 without having to reinstall XP?
Upgrading as well as installing/uninstalling any VMware product like Fusion, Player or Workstation does not touch the virtual machines. Just make sure the virtual guest is cleanly powered down (not suspended)!
