If I already have Parallels Pro Control Panel, are all previous versions upgradeable to Parallels Pro Control Panel X?
Parallels Pro Control Panel X for Windows supports upgrades from the following versions: • Parallels Pro Control Panel for Windows version 4.0.0 • Parallels Pro Control Panel for Windows version 5.0.0 You can use import / export tools instead, if you prefer, to migrate from any of the above versions. If you are using Parallels Pro Control Panel for Windows version 3.6, there are specific migration tools for upgrading this version of server.
