CUCM upgrade process via cli

[@DoeBoy999]

Automation and orchestration with PCD is a godsend. Cisco Live presentations suggest this a lot nowadays. After using it on a few clusters I won't ever go back to manual.

I did a video on how to use PCD. Someone asked about how to do it with the CLI. I like using the CLI method at times.

Thank you, Chris!

Great content, as always, Patrick! Thank you! I have a question - Did we mention in the cli that the upgrade is meant to be for a Cisco 8851? Or does it do that for 8851 automatically? Sorry for my dumb question

[@PatrickKinane1]

Good question! The CLI commands for adding a cop file are the same commands used to upgrade the CUCM version using an iso file. Because the cop file used in this video is for 88XX model phones, more than just the 8851 phones would be upgraded. I was probably focusing on the 8851 for a lab recreate or something.

Great Video. I hope you won't mind sharing your inputs on below queries. We have CUCM version 9.1 running and we have to upgrade it to version CUCM 12.5. Can we upgrade it directly or should we first upgrade to CUCM version 12 as ESXI version required for CUCM 12.5 is ESXI 6.5 UCS version running is UCS C220 M3S which is also end of sale and hardware support is about to end. So what you suggest should we move to CUCM cloud set up or should we get UCS C220 M5 or UCS C240 M5 We have this cluster of 3 nodes. To upgrade which method we need to prefer. I mean using PCS or manually.
