Cluster upgrade

Sergei Tikhomirov

This article provides guidance on upgrading an ADPS cluster to a newer version.

Upgrade process

To upgrade an ADPS cluster, you need to upload the new ADPS bundle to ADCM. Once uploaded, ADCM recognizes the fresh bundle version and the Upgrade cluster action appears in the ADCM UI.

CAUTION

When you upgrade an ADPS cluster, the products must be upgraded in the following order:

  1. ADCM

  2. ADPS

  3. ADS / ADH

Upgrade ADPS with SSL enabled

In the ADPS cluster SSL is enabled via Knox. While upgrading, keep an eye on the gateway.tls.key.alias parameter in the Knox service configuration. It should be set to an actual alias of a Knox host (e.g. its FQDN). Make sure to restart Knox after changing and saving the value.

After that is done you can upgrade your ADPS cluster as usual.
