This section provides information about MySQL Cluster software and table file compatibility between different MySQL Cluster NDB 7.5 releases with regard to performing upgrades and downgrades as well as compatibility matrices and notes. You are expected already to be familiar with installing and configuring a MySQL Cluster prior to attempting an upgrade or downgrade. See Section 19.3, “Configuration of MySQL Cluster”.
Only compatibility between MySQL versions with regard to
NDBCLUSTER is taken into account in
this section, and there are likely other issues to be
considered. As with any other MySQL software upgrade
or downgrade, you are strongly encouraged to review the relevant
portions of the MySQL Manual for the MySQL versions from which
and to which you intend to migrate, before attempting an upgrade
or downgrade of the MySQL Cluster software. See
Section 2.11.1, “Upgrading MySQL”.
