[CalendarServer-users] Updating version

[jean]

hello,

I try to update version vith an SVN update...
but after that, server doesn't work anymore, log says that all  
registrated users (their guid) are wrong...
what can I do if I don' t want to loose all my verved calendars ?
(I can come back to the older version, or erase all calendars to keep  
the new version, but that' s not what I would like to do)
