Upgrading from MariaDB 10.0 to 10.1 under Windows
Upgrading from MariaDB 10.0 to 10.1 on a Windows System. Must i do some especial thing with a master slave replication system? Which one must I update first master or slave?
Answer Answered by Daniel Black in this comment.
Backward compatibility is assured. If a master on 10.1 generated a binary log message that the slave couldn't understand then replication would stop therefore don't do this. Always upgrade slaves before masters. No other special action is required in a replication configuration.
