Upgrade from ispmanager lite, pro, host to ispmanager business

It is not possible to upgrade from ispmanager lite, pro, host to ispmanager business on the same server. You have to install a new server for ispmanager business because the products have different architecture and software applications.

We strongly recommend a clean install of ispmanager business on a new server. Then you can import user data.

For more information please refer to the article How to move ispmanager from one server to another.
