Yes. If your project has grown and needs its own dedicated environment, the platform gets installed on your own server — that's the Server tier: the very one qwetru.ru itself runs on. The site moves along with its content and structure.
This tier is aimed at organizations: a company, an association, a publisher — anyone who needs their own rules about who gets an account, and their own space for projects and people. The price is negotiated and depends on the scope of work; there's deliberately no fixed price list. A private author usually has no need to move: on the Creative tier, you already get as many domains under one panel as you like.
Terms are discussed individually — write to info@qwetru.ru.
