14.4 Downgrading the InnoDB Storage Engine

Prior to MySQL 5.5, some downgrade scenarios involved switching the separate instance of InnoDB known as the InnoDB Plugin back to the built-in InnoDB storage engine. In MySQL 5.5 and higher, the features of the InnoDB Plugin have been folded back into built-in InnoDB, so the downgrade procedure for InnoDB is the same as the one for the MySQL server. For details, see Section 2.12, “Downgrading MySQL”.
