[horde] Merging H4 and H5 databases

[Simon B]

Hi.

I would like, if possible, to merge my test H5 db (both mysql) with
the production H4 db.  Obviously the schema is different, and my idea
was to:

- couple the H4 database to the new H5 install
- upgrade the schema
- merge the databases

The last step is where I'd need some help.  Is this possible?  I'm
presuming I can just inject all the sql commands from the H5 db into
the newly upgraded H4 db.

In the worst case, I could always export the addressbooks and
calendars of the test users - but is quite a labourious task.

Any advice gratefully received.

Thanks.

Simon
