Perform the upgrade so that services are upgraded in the following order:
1 IaaS Web sites
If you are using a load balancer, disable traffic to all non-primary nodes.
Finish the upgrade on one server before upgrading the next server that is running a Website service.
Start with the one that has the Model Manager Data component installed.
If you are performing a manual external Microsoft SQL database upgrade, you must upgrade the
external SQL before you upgrade the Web node. You can upgrade the external SQL remotely from
the Web node.
2 Manager Services
Upgrade the active Manager Service before you upgrade the passive Manager Service.
If you do not have SSL encryption enabled in your SQL instance, uncheck the SSL encryption
checkbox in the Iaas Upgrade configuration dialog box next to the SQL definition.
3 DEM orchestrator and workers
Upgrade all DEM orchestrators and workers. Finish the upgrade on one server before you upgrade
the next server.
4 Agents
Finish the upgrade on one server before you upgrade the next server that is running an agent.
5 Management Agent
Is updated automatically as part of the upgrade process.
If you are using different services on one server, the upgrade updates the services in the proper order.
For example, if your site has Web site and manager services on the same server, select both for update.
The upgrade installer applies the updates in the proper order. You must complete the upgrade on one
server before you begin an upgrade on another.
Note If your deployment uses a load balancer, the primary appliance must be connected to the load
balancer. All other instances of vRealize Automation appliance appliances must be disabled for load
balancer traffic before you apply the upgrade to avoid caching errors.
