We are running the software version of the management gateway and need to migrate to the appliance before we upgrade to LANDesk 9. Is there a document out there that will cover this? All the papers I have found only pertain to new installations.
There is no migration per se like there is for LDMS. You will have to setup the appliance and configure it from scratch. Just remember to reconfigure your clients after the appliance is up and running. There really is not that much to configure on the appliance, and just follow the docs.
