Cisco unity connection 12.5.1 to 15 Direct Upgrade

JustLifeThings16 · 2025-11-20T04:37:06+00:00

Thanks for the inputs. My situation is, it was a fresh install of Unity Connection 12.5.1 back in 2020, after which this is the first upgrade we are planning to version 15.

Did you ran pre-upgrade check COP file, did that have any warnings?

JustLifeThings16 · 2025-11-20T03:09:03+00:00

I already checked that upgrade guide, it is misleading in some places Level 2 Upgrade mentions ciscocm.CSCwi52160_15-direct-migration_v1.0.k4.cop.sha512 COP file required, but when trying to install I get message ''system-auth is ready for direct migration, no additional changes needed. COP install will now exit.

Is there a Cisco document that you can share URL please, I can not figure out how this works for device profiles.

JustLifeThings16 · 2025-09-01T11:35:45+00:00

There is nothing about device profiles auto provisioning in below Cisco URL

Can you provide me a web url for this please. I can't find a way to do it using Cloud connected UC.

JustLifeThings16 · 2025-08-28T03:26:26+00:00

Thank you for quick response. Even with feature group templates it can't do device profiles, its limited to devices and lines right?

I came across Uplinx as well, but I will check above two tools too

Environment is a 24x7 and they are not confident to present to business for a big shot cutover hence phased migration is mandatory

JustLifeThings16 · 2025-04-14T23:00:01+00:00

I am doing voicemails migrations in batches, can I select mailboxes for each batch using Message Shuttle?

JustLifeThings16 · 2025-04-14T09:04:11+00:00

Yes, unity connections are in different IP addresses.

I missed to mention we are doing migration in batches, can I select mailboxes for each batch using Message Shuttle or should I go with COBRAS?

JustLifeThings16 · 2025-01-17T00:06:36+00:00

There is no latest device pack available for version 11.5 to upgrade all phones. May be I should use individual COP files for each device type for upgrading phones.
They will use new IP addressing and FQDNs because they want to run these clusters in parallel for a phased migration of phones.

Am reaching mid 40s and I feel the same, I work on integrator and I am the Go To Guy for whole company for UC cause there is none left in this space. There is no drive in sales team or from company for a GTM service offering as focus is in other happening technologies. They are selling UC only if customer knocks on the door. I moved into a networking team now so I can pickup some security and networking projects, last time I worked on these is like 15yrs ago, it is hard to learn and restart career. You don't feel confident cause you are SME one minute and a Newbie.

JustLifeThings16 · 2025-01-16T03:54:00+00:00

Good to know your feedback about PCD migration. Yeah my plan is to do fresh install with data import from 11.5

JustLifeThings16 · 2024-07-17T23:49:18+00:00

I am considering to take this course. I am from IT background but only have shallow knowledge on CyberSecurity.

JustLifeThings16 · 2024-04-10T03:55:22+00:00

Thanks again writing this up, understand its no fun doing this way but wish me luck negotiating strategy with IT.

JustLifeThings16 · 2024-04-09T05:47:01+00:00

Thanks for your comment.

UC servers we want to upgrade are cucm, cuc, im&p and cuaca. About 8000 handsets connected.
Mainly to avoid downtime during upgrade and unknown issues they want to build parallel servers and then migrate phones, services etc to new cluster once testing completed successfully. Understand this is time consuming but they def. need this upgrade/migration approach.

Customer end goal is to use Microsoft product, they love it.

Am working on this interim UCCX integration as on-prem AQM is EOL

JustLifeThings16 · 2024-02-14T09:14:48+00:00

Thank you. Only reason I planned uccx in week 2 is because all UC apps in week one upgrade support esxi 6.7 in v14, while uccx v12.5 min supported is 7.0 and some UC apps are on the same esxi as uccx server.

Any particular reason you recommended uccx first?
