Just follow the directions in the
latest release under:
Upgrading from XOOPS 2.0.* above 2.0.14 and 2.2.* (using the full package)
Before you do it:
* make a copy of you database and all files
* make a dry run on your local PC using
WAMP or similar server and your real data from your server
* be aware that some of the old modules might not work, so you'll need to update them as well, or replace them with others
Give us a list of the modules you have and maybe we can help you with replacements.
But the most important thing - make a dry run on your local PC before you touch the real installation
