I purchased Zentyal Commercial 6.0 and I am interested in upgrading to 6.2, but I don't see any documentation that references upgrading the commercial version. It seems all of the documentation for upgrading is for the Development version and the only way to upgrade the Commercial version is with a support ticket, which has a cost. For a home user, that is not a desired method of upgrade and I would prefer to perform the upgrade myself if I have documentation available to me.
