This portion of the MySQL Cluster chapter covers upgrading and downgrading a MySQL Cluster from one MySQL release to another. It discusses different types of Cluster upgrades and downgrades, and provides a Cluster upgrade/downgrade compatibility matrix (see Section 2.6.2, “MySQL Cluster 5.1 and MySQL Cluster NDB 6.x/7.x Upgrade and Downgrade Compatibility”). You are expected already to be familiar with installing and configuring a MySQL Cluster prior to attempting an upgrade or downgrade. See Chapter 3, MySQL Cluster Configuration.
For more information about upgrading or downgrading between MySQL Cluster NDB releases, or between MySQL Cluster NDB releases and mainline MySQL releases, see the changelogs relating to the applicable MySQL Cluster versions.
This section remains in development, and continues to be updated and expanded.
