If you are currently running CloudAccess 2.0 in your environment, you can use the update channel to upgrade to CloudAccess 2.1. For more information, see Section 9.5, Updating the Appliance.
Upgrades from previous versions through the update channel are not supported. If you have a previous version installed, you must manually upgrade to CloudAccess 2.0 and then use the update channel to upgrade to 2.1, or perform a fresh installation of CloudAccess 2.1. For more information about upgrading your environment from CloudAccess 1.5 to CloudAccess 2.0, see “Upgrading Your Environment” in the NetIQ CloudAccess and MobileAccess Installation and Configuration Guide for CloudAccess 2.0 on the NetIQ Documentation website.
