When upgrading from one version of moregroupware to the next it is recommended that you do so via a clean installation. To upgrade otherwise requires an advanced knowledge of SQL and a lot of "hacking" to your database.

An automatic upgrade function is being worked on, and as soon as it is available it will be released, but until then we highly recommend you re-install from a clean empty database.

If you want to try an upgrade, you should look for upgrade instructions on the mailing lists. A mail with instructions will be posted for every release, and should ease an upgrade. Those instructions can be found in an appendix to this manual as well.
