mariadb/mysql-test/suite/galera/t/galera_migrate.test

#
# Execute a migration from MariaDB replication to Galera replication.
# The test starts with 4 stand-alone servers defined by galera_migrate.cnf and then
# performs the following steps:
#
# 1. Begin with a single MySQL server
# 2. Establish traditional MySQL master-slave replication
# 3. Attach a new sever to serve as a MySQL replication slave
# 4. Enable Galera on the new slave and create a single-node Galera cluster
# 5. Attach a second Galera node
# 6. Turn off the traditional replication parts of the system
# 7. Continue replicating within Galera only
