Before you upgrade the VMware Identity Manager virtual appliance offline, perform these prerequisite tasks.

Verify that at least 2.5 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.

Confirm that a VMware Identity Manager upgrade exists. Check the My VMware site at my.vmware.com for upgrades.

Prepare a local Web server to host the upgrade file. See Prepare a Local Web Server for Offline Upgrade.
