hi, i'm trying to export all users address books for a mail server migration (roundcube 0.9.2 to zimbra). some of the users have around 100-500 contacts grouped into several groups.

i was able to export and import all the contacts by exporting the 'contacts' table from mysql to a csv file, but then i don't have the groups info.

any ideas about how can i migrate the groups info from the address book?
