You can check for updates from the client management page for your appliance and download the updates by using one of several methods.

You can download the update for your Identity Appliance or vCloud Automation Center appliance from a public repository on the vmware.com Web site.

If your Internet access is restricted, you can set up your own internal repository for updates, instead of getting updates from a VMware public repository. You can download updates as a zipped update bundle.

You can update your virtual appliance from an ISO file that the appliance reads from the virtual CD-ROM drive.
