[cisco-voip] CUCM Upgrade

[H, Tim]

I ended up looking at the ReadMe for the upgrade.  I went ahead and upgraded all of the phones to the version it will be at upgrade time to avoid all phones downloading the new firmware at once.

Thanks for the suggestions!

Yes, you could do that and that would definitely keep your phones from getting the new firmware. Good idea!

If I'm not mistaken, you can upgrade the publisher first, change the device defaults, then upgrade the subs. We've been doing something similar on 4.1 for years.

No, that won’t do it because the upgrade will change it to the latest version. It would need to be changed on the phones.

You could also change the device defaults firmware config parameters.

I had a customer do this last Sunday. The only change was the firmware. Attendant Console was unaffected. If you don’t want to deal with the firmware, you could hard code the firmware on the phones until you are ready for the jump because the old firmware will stay on the server.

All,

I'm getting ready to upgrade our CUCM cluster from 7.02 to 7.15.  I'm aware of the firmware jump as you have to upgrade to 8.52sr1 or whatever, but is there anything else I need to be cautious about?  Looks like the attendant console might change a bit in the version jump, but should still function?

Any other caveats that anyone have ran into would be helpful.

Thanks,
Tim
