Howdy all,
Some of you have noticed that virtual server limits are being enforced in Virtualmin, as of a couple of revisions ago. I've finally added upgrades to the shopping cart, so folks hitting those limits can easily get a bigger license.
The upgrades are processed manually, as I haven't written the custom module to associate serial numbers with upgrades purchased, so it'll take up to 24 hours for upgrades to take effect, unlike Software category purchases, which are available immediately.
Pricing is simply the difference between two license types. We don't have any interest in punishing you for starting small or for being more successful now than you were when you first purchased!
As always, let us know of any questions or comments you might have.
