Migration from MySQL to MariaDB

Thanks for the advice. Worked flawlessly:

  1. Database backup
  2. occ maintenance --on
  3. service mysql stop
  4. apt-get remove mysql-server & apt-get autoremove (mysql-server-5.5, …)
  5. apt-get install mariadb-server with current dependencies (mariadb-server-10.0, …)
  6. occ maintenance --off

Nextcloud starts without any errors beside:

Fatal webdav Sabre\DAV\Exception\ServiceUnavailable: HTTP/1.1 503 System in maintenance mode.

Maybe this could be changed from Fatal to Info as it is totally expected during maintenance mode :wink: .
