Minor Upgrade

:information_source: Example: MySQL Router 8.0.33 -> MySQL Router 8.0.34
(including simple charm revision bump: from revision 99 to revision 102)

We strongly recommend to NOT perform any other extraordinary operations on Charmed MySQL cluster and/or MySQL Router, while upgrading. As an examples, these may be (but not limited to) the following:

  1. Adding or removing units
  2. Creating or destroying new relations
  3. Changes in workload configuration
  4. Upgrading other connected/related/integrated applications simultaneously

The concurrency with other operations is not supported, and it can lead the cluster into inconsistent states.

:warning: NOTE: Make sure to have a Charmed MySQL backups of your data when running any type of upgrades.

:warning: TIP: The “MySQL Router” upgrade should follow first, before “Charmed MySQL” upgrade!!!
