Upgrading CUCM 7.0.2 to 8.6 questions

[Ahmad Usman Anwar]

I have two questions about upgrading Call Manager 7.0.2 to Communications Manager 8.6 on one publisher and one subscriber: They are currently running Cisco Teleprence rooms (CTS-3010's) as well as conferece stations.

- Can I upgrade directly from 7.0.2 to 8.6, or is there an incremental upgrade I need to do?

- Do I need to do any manual phone, codecs upgrades, or will this take place automatically after the CM servers are upgraded?

Regards

Check out this doc:

You need intermediate upgrade, i.e. version 7.1.

@Chris Deren, Thanks for the response.

I believe the appropriate upgrade path would be from 7.0.2 - 7.1.5 - 8.6.2, However I would like to inquire over potential implications to the present Call Manager setup and configuration with regards to IP Phone firmwares, Telepresence Room Codec (this is a CTS 3010 deployment) and IP Phone firmwares etc.

Would the firware loads be automatically upgraded?
