  When migrating from the standard MySQL implementations to Galera Cluster, there are some additional steps that you need to take to ensure that you safely transfer the data from the existing database to the new cluster.  This section covers the procedure to update system tables and how to migrate from stand-alone MySQL, as well as from MySQL primary-replica replication clusters.
