[cisco-voip] Device pack installation methodology question

[Terry Cheema]

The easiest way I have found is using imort/export function to keep the firmware same. The below steps should do:
1) Export the device defaults
2) Install the cop file on the pub and the subsequent nodes (after the installation is complete loads will be updated)
3) Import the device defaults to revert back to previous firmware.
4) Once confirmed the loads are same as per the original - Reload the servers one at a time.

Once the publisher is backup, set all the device defaults back to what I want them to be then add the publisher back to the CM Group. Then drop the subscriber from the CM Group forcing all the phones on the publisher and start the install process over for the subscriber. Once everything is back up add the subscriber back to the CM Group.

As long as both nodes are running call processing, they'll fail over when the node reboots.  Not sure about on 9.X, but on 10.X this just shows as a blip on the phones of them reregistering, not a full reboot.  Obviously if you install new software for those phones, they'll upgrade software when they reboot.
