Jan, far be it from me to call you a liar, but you're far too modest.
Your DB structure for Kronolith is quite solid.
For anyone else finding this thread, this is what I did..
Backed up the H4 db to a new db named h4backup.
Granted rights to the horde mysql user to this h4backup db
Changed the config/conf.php to use the new h4backup.db
Logged in as the Administrator and updated all the schemas.
Use mysqldump to create a hordebeta.sql from the hordebeta (H5) db
Use mysqldump to create a h4backup.sql from the h4backup db
Open the hordebeta.sql with an editor and string replace hordebeta with h4backup
Concatenate the two .sql files (hordebeta.sql >> h4backup.sql
mysql -u root -p < h4backup.db
One user has some duplicate appointments, but I think this is a legacy
issue with one of her mobile clients. So far no other issues.
