Hi,
just updated the 'how-to' on page 1 with an upgrade part.
Did some first tests and so far did not find a problem (for what it is worth: been using eGroupware for years and never had one upgrade problem, this makes me a 'bad' tester

).
Will be spending some time to see what changes where made in the SyncML part of eGroupware: hope to sync my Android address book using Funambol to my eGroupware server.
Will also convert this how-to to the wiki how-to section, this forum thread will be used for updates, notices, discussion, support, etc.
Have fun!
regards,
Ruud.
