Lifetime Plesk License
Could you please clarify your feature request? What is desired scenario and benefits of that?
If you have a valid actual lease (month/year) license then you are able to do upgrades w/o additional payment to the latest available Plesk version, which doesn't require OS upgrade. I mentioned OS upgrade explicitly because some major OS versions don't support an upgrade.
I do not think so. I would like to pay, for example, 150 € for all 4 years of the license, but once, instead of the annual 45 €. Also, what will happen to the installed panel when the version becomes obsolete?
Fedor, would annual purchase also work for you?
As an example of such a model, I can cite MS Office 365 and 2016. 365 - permanent payments, 2016 - a one-time purchase for one edition.
I would like to be able to get a lifetime license for Plesk through a one-time purchase. In my opinion, this version of licensing is suitable for Web Admin Edition. A lifetime license will allow site owners to stop controlling their expenses on Plesk. Personally, I'm more pleased to pay one-time and know that the control panel will always work.
