Kolab migration on debian

[Johannes Ranke]

Hi all,

I upgraded my kolab 16 on Debian system from Debian 9 to Debian 10 yesterday, 
in the way sketched out by Christoph in the mail below. It went fine, but I had 
the following unexpected problems:

- In Kmail, my IMAP folder for that server disappeared. It reappeared after 
disabling server-side subscriptions
- I could not connect to contacts, calendar and tasks via DAV at first, and had 
the following errors in my iRony errors.log:
[0x-Nov-2021 xx:xx:xx Europe/Berlin] PHP Fatal error:  Uncaught Error: 
Undefined class constant 'MYSQL_ATTR_FOUND_ROWS' in /usr/share/roundcubemail/
program/lib/Roundcube/db/mysql.php:149

It turned out that the upgrade did not remove php7.0 from stretch, it was kept 
alongside php7.3 from buster. After removing php7.0 and enabling the php7.3 
apache module, the error went away.

Cheers,

Johannes
