<div dir="ltr">I need to install a device pack on a 2 node 9.1(2)

<br>
The approach I am going to use is:<br>
<br>
Drop the publisher out of the CM Group, forcing all phones to
the subscriber. Install the device pack on the publisher and
reboot the publisher. 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.<br>
<br>
Does that sound reasonable or is there an easier way?<br>

Any time I've needed device support I just install it on all the
nodes then reboot them one at a time during a maintenance window.
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.<br>
