Hi there, is it possible to install a copy of my licensed Xenforo installation on a different server, so that we can test things like upgrades / major changes before making them to the live system?
You may create additional test installations for the purpose of testing the Software. Any test installation of this kind must be password protected, installed at a URL that makes the testing purpose clear, not used for production purposes and access to it must be limited to You and Your website staff.
The license permits one publicly accessible installation and one test installation, which must be password protected and accessible by you and your site staff only.
