16.4.2. Replication Compatibility Between MySQL Versions - 0 views
-
MySQL supports replication from one major version to the next higher major version. For example, you can replicate from a master running MySQL 4.1 to a slave running MySQL 5.0, from a master running MySQL 5.0 to a slave running MySQL 5.1, and so on.
-
However, one may encounter difficulties when replicating from an older master to a newer slave if the master uses statements or relies on behavior no longer supported in the version of MySQL used on the slave. For example, in MySQL 5.5, CREATE TABLE ... SELECT statements are permitted to change tables other than the one being created, but are no longer allowed to do so in MySQL 5.6 (see Section 16.4.1.4, “Replication of CREATE TABLE ... SELECT Statements”).
-
Important It is strongly recommended to use the most recent release available within a given MySQL major version because replication (and other) capabilities are continually being improved. It is also recommended to upgrade masters and slaves that use early releases of a major version of MySQL to GA (production) releases when the latter become available for that major version.
