convert horde - sql based data to imap

[Achim]

Hi all,

I am quite new to kolab - actually to ClearOS...

My old server was courier-mta based with mysql based virtual user
accounts. Horde user data is stored also in mysql.

Now I am in the midst of migrating the server over to kolab/ClearOS and
have the biggest difficulties. Is there a tool to convert my turba
addressbook and kronolith calendar data?

Greetings - Achim
