MySQL 8.4 Reference Manual  /  Upgrading MySQL  /  Upgrade Paths

3.2 Upgrade Paths

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

  • We recommend checking upgrade compatibility with MySQL Shell's Upgrade Checker Utility before performing an upgrade.

  • A replication topology is upgraded by following the rolling upgrade 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 upgrade.

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

Table 3.1 Upgrade Paths for MySQL Server

Upgrade Path Path Examples Supported Upgrade Methods
Within an LTS or Bugfix series 8.0.37 to 8.0.41 or 8.4.0 to 8.4.4 In-place upgrade, logical dump and load, replication, and MySQL Clone
From an LTS or Bugfix series to the next LTS series 8.0.37 to 8.4.x LTS In-place upgrade, logical dump and load, and replication
From an LTS or Bugfix release to an Innovation release before the next LTS series 8.0.34 to 8.3.0 or 8.4.0 to 9.0.0 In-place upgrade, logical dump and load, and replication
From an Innovation series to the next LTS series 8.3.0 to 8.4 LTS In-place upgrade, logical dump and load, and replication
From an Innovation series to an Innovation release after the next LTS series Not allowed, two steps are required: 8.3.0 to 8.4 LTS, and 8.4 LTS to 9.x Innovation In-place upgrade, logical dump and load, and replication

From MySQL 5.7 to an LTS or Innovation release MySQL 5.7 to 8.4 A bugfix or LTS series cannot be skipped, so in this example first upgrade MySQL 5.7 to MySQL 8.0, and then upgrade MySQL 8.0 to MySQL 8.4.
