This document describes possible issues when upgrading MariaDB MaxScale from version 6 to 22.08.
For more information about MaxScale 22.08, refer to theChangeLog.
Before starting the upgrade, any existing configuration files should be backed up.
The support for legacy encryption keys generated with maxkeys from pre-2.5
versions has been removed. This feature was deprecated in MaxScale 2.5 when
the new key storage format was introduced. To migrate to the new key storage
format, create a new key file with maxkeys and re-encrypt the passwords withmaxpasswd.
The deprecated Database Firewall filter has been removed.
