1. backup the entire DB
2. copy all files over to the new server from the old one
3. if you are changing domains or the new server paths are different, you will need to edit the config.inc.php to reflect that
4. import the DB into your NEW server and verify current _non_ upgraded version is still running
5. then upload the 7.5.6 new stuff (only files required as in the readme) -- including install directory
6. run install/upgrade.php
--> forum is 7.5.6
