Postgres major version upgrades on Hybrid Manager—single node or High Availability clusters

Suggest edits

Prerequisites

The prerequisites to get started are to have a cluster created with HM up and in a healthy state.

To ensure the cluster is in a healthy state, from the cluster's main page, select the Monitoring tab. Now check the cluster and database metrics and make sure everything is operating and all metrics are within the defined acceptable parameters.

Upgrade the PG major version of an existing cluster created with HM

  1. First, from the cluster's main page, select Quick Action>Upgrade Cluster and then choose Major Upgrade.

  2. The Upgrade Cluster — Major dialogue window opens.

  3. Select your preferred new major version image.

  4. Review the upgrade path and confirm by selecting the Continue button.

  5. The dialogue window now shows the specific package changes to be expected with the upgrade. Review these and select Upgrade Cluster if everything looks as correct.

  6. The upgrade is applied automatically. You can then use the Monitoring, and Logs tabs to monitor the process and/or troubleshoot any unexpected behavior.

Note

On rare occasions, additional steps might be recommended after the major upgrade is completed for certain product release. Consult the Release notes for the product in question to see if this is necessary in your case.

Rollback considerations

There is no automatic rollback available with this approach and performing a downgrade is not recommended. To undo the minor upgrade, restore from the latest backup in a new cluster running the preferred minor version and switching application workloads over to the new cluster. You can then delete the PG minor upgraded cluster or troubleshoot it further.
