I've been running Zentyal and Zarafa for long now and when 3.4 was released I emediate tried to upgrade via button on Admin page.
The upgrade failed and left system in unusable state.
I reinstalled 3.3 and restored configuration from backup and uninstalled Zarafa, (since it has been removed in 3.4) did a new backup and tried to upgrade again. No luck.
I did a clean 3.4 install and tried to restore the newly made backup from 3.3 (without Zarafa). That left me with an unusable webserver and unremovable leftovers with references to groupware (Zarafa) in at least Network -> Services.
I've given up migrating ALL settings to 3.4 from 3.3, and have limited my whiches just to be able to migrate users account, so that the users can keep their profiles and settings. Computer account would be grate to, but is not an issue (less than 10 computers to rejoin the domain)...
I even tried to install an virtual 3.3 and restored the backup, and on the 3.4 pointed out the virtual server as master, but got an ugly error.
Stumbled over an article about some script in Zentyal that unconfigured modules, but i cant find it again...
What do You suggest I should do to restore the users (and computers)?
Restore a 3.3 backup to the 3.4 system and unconfigure all modules except Users?
Sync the 3.4 server with a virtual 3.3 server and then change to standalone?
What are my choises...?
