Steps in the Upgrade Tool’s Automated Workflow
This section describes the steps that are automatically completed by the Cluster Upgrade Tool.
1. To prepare the Subscriber nodes for upgrade, a patch that provides required API support is
automatically installed by the Upgrade Tool on every Subscriber.
The Cluster Upgrade Tool uses remote API calls to control and monitor upgrade progress on the
subscribers.
To install the patch for API support on the subscribers, subscribers must be able to access the publisher over
HTTP, or they must be able to access the publisher over HTTPS using its hostname and validate the certificate
that is presented (trust the issuer and match the hostname in the certificate CN).
2. After you select the Subscriber nodes and click Upgrade, the upgrade image is copied to the Subscribers
you selected.
The Subscriber nodes copy the upgrade image over an HTTPS connection to the Publisher.
If the upgrade image is already present on a Subscriber node (you have downloaded it from the
Software Updates portal, or uploaded it in the Software Updates portal), the existing upgrade image on
the subscriber will be used for the upgrade.
3. If the Standby Publisher settings were configured, they are temporarily disabled. This setting is restored
after all subscribers have been upgraded.
