This section provides information about MySQL Cluster software and table file compatibility between MySQL 5.0 releases with regard to performing upgrades and downgrades.
Important
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 2.4.17, “Upgrading MySQL”.
The following table shows Cluster upgrade and downgrade compatibility between different releases of MySQL 5.0:
Notes.
MySQL 5.0.2 was the first public release in this series.
Direct upgrades or downgrades between MySQL Cluster 4.1 and 5.0 are not supported; you must dump all
NDBCLUSTERtables using mysqldump, install the new version of the software, and then reload the tables from the dump.Online downgrades from MySQL Cluster 5.0.12 to 5.0.11 (or earlier) are not supported.
You cannot restore with ndb_restore to a MySQL 5.0 Cluster using a backup made from a Cluster running MySQL 5.1. You must use mysqldump in such cases.
There was no public release of MySQL 5.0.23.
