Before you upgrade the VMware Identity Manager virtual appliance online, perform these prerequisite tasks.
Verify that at least 4 GB of disk space is available on the primary root partition of the virtual appliance.
Take a snapshot of your virtual appliance to back it up. For information about how to take snapshots, see the vSphere documentation.
If you are using an external database, take a snapshot or backup of the database.
Verify that VMware Identity Manager is properly configured.
Verify that the virtual appliance can resolve and reach vapp-updates.vmware.com on port 80 over HTTP.
If an HTTP proxy server is required for outbound HTTP access, configure the proxy server settings for the virtual appliance. See Configure Proxy Server Settings for the VMware Identity Manager Appliance.
Confirm that a VMware Identity Manager upgrade exists. Run the appropriate command to check for upgrades. See Check for the Availability of a VMware Identity Manager Upgrade Online.
