[cisco-voip] Device pack installation methodology question

[Anthony Holloway]

I just did this recently too, to add support for an 8831 on an 8x cluster.

Trying to recall from memory, here's what I recall doing:

1. Deactivate TFTP on both nodes
2. BAT Export the Device Defaults
3. Install the Dev Pack on Pub
4. Restart Pub
5. Install Dev Pack on Sub
6. Restart Sub
7. BAT Import the Device Defaults
8. Activate TFTP on both nodes
9. Add new 8831's

For step 7, I also did a BAT export of device defaults post dev pack, and
ran a diff on the two.  I saw the changes to the existing phone firmware as
well as the addition of the new phone models.  When you import the old
device defaults back in at this stage, note that the absence of the new
phone models simply tells CUCM BAT process to ignore them and leave them
alone, while reverting the firmware changes on all of the existing phones.
