Magento Commerce Cloud allows a service downgrade for any particular environment; the downgrade process is not as direct as upgrading, but it is still very convenient.
When downgrading a service, its version needs to be compatible with the Magento host version. The following table can be referenced for helping to determine the correct service version.
|Service||Adobe Commerce 2.4.x||Adobe Commerce 2.3.5 ~2.3.9|
|elasticsearch||7.7, 7.9||6.8, 7.5, 7.7, 7.9|
|mysql/mariadb||10.2, 10.4||10.1 ~10.3|
|redis||5.x, 6.x||5.x, 6.x|
The easiest way for downgrading a service is by renaming it or creating a new one in the magento/services.yaml file. For example:
Original service definition:
Updated service definition:
After that, the services relationship must be updated in the .app.magento.yaml file. For example:
Original service relation:
Updated service relation:
Commit the changes and push the changes for activating a redeploy:
git add –all
git commit -m “Downgraded elasticsearch service”
git push <remote> <branch>
After redeploying open a tunnel via Magento CLI:
And check the service version for confirming the upgrade:
After confirmation, the environment can be used as normal.
