[turba] Upgrading Turba 2.3.2 -> 3.0.10 (Stable)

[zBit]

Hello,

We need to upgrade our Horde webmail (H3.3.5 + I4.3.5 + T2.3.2) because of several problems (e.g. regarding attachments).
So far I have deployed new stable installation (H4.0.11 + I5.0.14 + T3.0.10) using the preferred way - pear - on our development
machine, changed a little overall settings using the Horde GUI administration site. As far as Turba is concerned, I merely renamed
sources.php to backends.php. The conf.php file as well as other Turba configuration files seem to be almost the same in both old
and new installations. I have imported old data into new database and run all available migrations from within the GUI administration.
The migrations finished without any problem as I can tell. Having both Horde and IMP ready I logged into an random e-mail account
but the address book looked pretty empty. Whatever account I choose its contact list is empty. I read all available (faq/install/upgrade)
guides but did not stumble accross something interesting in my problem. Therefore I have enabled debug while clicking on the
addressbook and it generated quite different SQL queries for both old and new installation. I do not know what should be wrong with
my configuration or where else to look at. Do you have any idea?
