Upgrade

This section contains documentation about performing upgrades (and rollbacks) on:

MySQL Server (workload)
Juju version

MySQL upgrades (workload)

There are two types of in-place workload upgrades:

Major upgrades - E.g. MySQL 8.0 → MySQL 9.0
- Not supported
Minor upgrades - E.g. MySQL 8.0.33 → 8.0.34 (includes charm revision bump)
- See: How to perform a minor upgrade
- See: How to perform a minor rollback

This charm only supports in-place minor upgrades.

To upgrade to a major MySQL version, one must install a new cluster separately and migrate the data from the old to the new installation. This documentation will be updated with the migration instructions when a new MySQL version becomes available.

Juju upgrades

New revisions of the charm may require that you do a major or minor Juju upgrade.

See the guide: How to upgrade Juju
