Anyone out there done this before?

I am not a Cisco Call Manager person. Our system has been up for almost 500 days. Rebooting tonight and I am worried about it not coming back. Going to pray before I run CLI command "utils system restart"

Cisco recommends that I take it to 12.5 and not all the way to 14.x

Looking for anyone with experience doing this. The Cisco steps provided might as well be in Chinese.

Not to scare you even more, but about 5 years ago we went to upgrade our Cisco phone system and it crashed hard. Plus we didn't have any backups. Cost us a lot of money to get back up and running. I wasn't directly involved since that's not my part of IT. My boss took a lot of heat for it and so did a couple of my coworkers.

Moral is to have a good backup? Or to migrate to cloud based phone system. That's the better solution in my opinion.

All of IT, no matter what your area of expertise is, comes down to a good backup and the occasional restore test.

It's the core / foundation. ...at least it should be! IT101

Open a TAC case if you need help/guidance. If you are not getting anywhere, feel free to ping me shaurobe (at) cisco (dot) com.

I am a Principal Engineer in CX and worked in TAC for 11+ years. Happy to connect the dots if you are not getting anywhere. I am a DC Apps/Software person, not a call manager person, but I could find someone to help you or find an answer if you cannot get it through a standard TAC case.

I appreciate the support. I have a TAC case open. It's slow, but moving.

Successfully rebooted the system last night and creating a procedure for it now.

Pretty simple, but there's a few things on our end that need to be touched i.e. Conference / Huddle rooms.

The case engineer has said she'll walk me through it, but the only problem I see is that they're gone at 5pm and that's usually about the time I can do anything.

Will see how it goes.

Always take two critical backups before any major change. The config on the device you're changing, in case things go wrong. And your resume, in case things really go wrong.

srob2004,

Here are the steps I have so far and have sent to the person working the TAC to confirm.

1. Manually backup CUC & CUCM
2. Pre-upgrade COP file
a. I need to verify the file name and location to put the file
3. Upgrade to 12.5(1)SU4?
a. Please confirm version and location to put file to execute
4. Post upgrade COP file
a. I need to verify the file name and location to put the file
5. Make sure all the phones register

What steps am I missing?

Sometimes it's days between emails with TAC.

Thanks, Gilligan
