There are 5 Primary Servers in a zone that uses the embedded database.
Server 1 is a Linux server with embedded PostgreSQL
Server 2, 3, and 4 are Appliance servers in which the Vertica-role is enabled
Server 5 is a Linux server
As a prerequisite, the Vertica cluster should be down. To bring down the cluster, you need to stop the Vertica services on all the servers in which Vertica is enabled. For more information, see the Vertica Reference guide.
Upgrade server 1. This is the first Primary Server that needs to be upgraded as it contains the embedded PostgreSQL.
Migrate server 2 and server 3 that are part of the Vertica cluster.
Migrate Server 4. As this is the last node in the Vertica cluster, you need migrate this server, only after Servers 2 and 3 are successfully migrated.
Run the Configure action microfocus-zenworks-configure-c Start to restart the ZENworks services on all the Primary Servers that have been upgraded up till now (server 1, server 2, and server 3)
Upgrade server 5.
There are 3 Primary Servers in a zone that uses the external database:
Server 1 is an Appliance server with Vertica enabled
Server 2 is an Appliance server but does not have the Vertica role enabled
Server 3 is a Windows server
Migrate server 1. This is the first Primary Server that needs to be upgraded as the Vertica role is enabled in this server.
Migrate and upgrade servers 2 and 3.
