When moving from MySQL 8.0 to MariaDB 10.11, please take note of the following incompatibilities:

* MariaDB's GTID is not compatible with MySQL's. Note that MariaDB and MySQL also have different [[gtid#system-variables-for-global-transaction-id|GTID system variables]], so these need to be adjusted when migrating.

409
* The [[authentication-plugin-unix-socket|unix_socket authentication plugin]] is now default on Unix-like systems, which is a major change to authentication in MariaDB. See [[authentication-from-mariadb-104|Authentication from MariaDB 10.4]] for an overview of the changes.
