As far as I know, upgrades with an ISO, MCT or GWX are all valid upgrade paths. Yes the ISO produced with the MCT is version specific. Run it and you will see for yourself. The only catch with using an ISO is using the correct version. Use the wrong one and you will be prompted to enter a key to upgrade.
