We are using vmProtect 8 and want to upgrade to Backup 12. What do we need to pay attention to?

An upgrade from vmProtect 8 to Backup 12 Virtual Host is possible.

Please note that there is a change in the licensing. vmProtect is licensed per CPU and Backup 12 Virtual Host is licensed per Host. You can perform a standard upgrade in your Acronis account page which will then update 2 CPU licenses of Acronis vmProtect to 1 license of Acronis Backup 12 Virtual Host.
