[turba] Migrating Turba contacts and groups between H4 and H5

[Andreas Rieger]

Hi,

we are currently in the process of migrating users between a Horde 4 and a
Horde 5 Installation.

One stumbling block is the migration of address books:

As far as i can see there is no easy option to export groups
(Verteilerlisten) and their corresponding members. Using the web interface
group memberships are lost.

Would it be an option to simply copy the relevant rows from the
turba_objects table between installations (adjusting the owner_id) but
keeping the object_ids? Or do i have to recreate the contacts so they get
new, unique IDs?

Has anyone done this before? 
Do I miss obvious easier options?

Thanks,
Andreas
