2. Use the command system upgrade, which will upgrade your second partition, then reboot. Policy Manager
boots into the upgraded image.
If you access the appliance via serial console, you should also be able to boot into the previous image by choosing
that image in the Grub boot screen.
3. Verify that all configuration and session logs are restored and all services are running. Also verify that node-
specific configuration such as the server certificate, log configuration and server parameters are also
restored.
Upgrade the Image on all Appliances
Perform these steps to upgrade the image on all appliances in a Policy Manager cluster.
1. Upgrade publisher Policy Manager first, and reboot into the new image.
2. On the first boot after upgrade, all old configuration data is restored. Verify that all configuration and
services are intact.
In the cluster servers screen, all subscriber node entries are present but marked as Cluster Sync=false
(disabled for replication). Any configuration changes performed in this state do not replicate to subscribers
until the subscribers are also upgraded (effectively no configuration changes are possible on subscribers in
this state).
You can add a subscriber to the cluster from the User Interface: Configuration > Administration > Server
Configuration (page) > Make Subscriber (link).
3. One node at a time, upgrade the subscriber nodes to the same Policy Manager version as the publisher,
using the same steps as for a single Policy Manager server. On the first boot after upgrade, the node is
added back to the cluster (the publisher node must be up and available for this to work).
4. Login to the UI and verify that the node is replicating and Cluster Sync is set to true.
If the publisher is not available when the subscriber boots up after the upgrade, adding the node back to the cluster
fails. In that case, the subscriber comes up with an empty database. Fix the problem by adding the subscriber back
into the cluster from the CLI. All node configuration, including certificates, log configuration and server parameters
are restored (as long as the node entry exists in the publisher with Cluster Sync=false).
