Chapter 4 Downgrading MySQL

Table of Contents

4.1 Downgrade Validation

Notes

• Make sure you understand the MySQL release model for MySQL long-term support (LTS) and Innovation releases before proceeding with a downgrade.

• A replication topology is downgraded by following the rolling downgrade scheme described at Section 19.5.3, “Upgrading or Downgrading a Replication Topology”, which uses one of the supported single-server methods for each individual server downgrade.

• Monthly Rapid Updates (MRUs) and hot fixes also count as releases in this documentation.

Important

Downgrading to MySQL 5.7 or earlier is not supported.
