My new site will not be forum site anyway, so I will start with wordpress. However, I like the current xenforo setup for testing different things, and I might need a forum later at site at www.domain. com / forum (and not domain.com as now).
What is the easiest way to make this transfer, can I just move all the files the new folder?
How can I move my installation to a different directory?
Update the Board URL in the ACP -> Options -> Basic Board Information and move the files to the new directory. You may need to restart the server for the change to take effect.
