UC Module V1 Upgrade 8.1 to 10.1 - My undocumented experience 2

[Nortel4Ever]

Last night I upgraded an IPO and its V1 UCM from 8.1 to 10.1. The IPO upgrade via the "recreate SD card method" was done in under 30 minutes, no problem. The UCM V1 upgrade was more than a little sketchy and definitely undocumented. I thought I would share my procedure and experience last night to possibly help someone else out:

Downloaded the UCM 10.1 .iso file from Avaya
Used the Avaya USB creator to format a USB drive as an Upgrade USB
Backed up the UCM
Put the upgrade USB into the top USB slot (VERY IMPORTANT!! as it will not work in the bottom slot - a lot of time wasted last night)
Used System Status to shutdown the UCM
Used System Status to perform a USB Boot
After about 5 minutes System Status will display USB Install/Upgrade with a progress indicator
The progress indicator will jump from 5% to 15% to 75% with about 20 minutes between each step.
After another 20 minutes at 75% I got an Upgrade Failure notification - WTF and much swearing!!
I removed the upgrade USB and rebooted the UCM
System status showed "starting" then "booting"
After about 30 minutes of "booting", it looks like it did two separate boots, then POOF, like magic the upgrade was done.
System Status now showed a functioning UCM running 10.1 software.


Hope this helps someone else in the future...

Is upgrading from 8.1 to 10.1 documented as Ok by Avaya?
I would have expected to have had to backup the UCM & then do a full reload

@IPGuru - I believe the only supported path is a full re-image. I'd be nervous about attempting anything unsupported on the UCM, although it seems it does work as Nortel4Ever found out. I'd be interested to hear if any issues arise.

Indeed Nortel4ever seems to have found a usable solution, hopefully it wont cause any future problems (& with the rep of the UC110 how would you know).

My experience with Linux in general leads me to believe that this will not be an issue as almost anything can be upgraded in situe only kernel upgrades need reboots

I did refer to the IPO Knowledge Base prior to the upgrade and it did confirm that the only supported method of upgrading a UCM from 8.1 to 10.1 is the USB method I used, and there are specific instructions for upgrading a V1 module. The mistake I made was using the wrong USB slot.
The failure at 75% occurred after it sat at 75% for about 20 minutes. I suspect that the upgrade was actually done at that point but for some reason the UCM could not restart with the USB still plugged in and it threw an error.
