You can do a Full High Availability upgrade with a clean installation on the secondary cluster member and synchronize the primary cluster member. This type of upgrade causes downtime to the cluster members.
To upgrade Full High Availability with a clean installation:
The secondary cluster member processes all the traffic.
Note - We recommend that you export the database using the Management Server Migration Tool.
Make sure version of the SmartConsole is the same as the server.
The primary cluster member processes all the traffic.
Note - Make sure that the For Gateway Clusters install on all the members option is cleared. Selecting this option causes the installation to fail.
Synchronization for Management High Availability starts automatically.
