and restriction ?????
For CUCM 8.5 to 8.6 upgrades the most important thing to be aware of is this.
Cisco Unified Communications Manager Version 8.6>Unified Communications Manager / CallManager / Cisco Unity Connection Utilities>COP-Files
Also remember that the upgrade involves a kernel upgrade and takes an extra 30 minutes to an hour. It's all covered in the release notes.

Joe, thanks for this information. I have lab where a Pub has been from 8.0.3 to 8.5.1 to 8.6.2 using the COP, no problem most of the time. However, when deplyoing a new Sub from scratch, I cannot install the COP during upgrade/patch routing in installation. Without that, the 8.6.2 upgrade patch fails during installation and trying to join 8.5.1 to the Pub will not work.
Is there a proper way to do that or should we always use a bootable DVD to re-install or deploy a new 8.6.2?
I had the same problem with joining a new Sub to an 8.6 cluster. I just downloaded the 8.6 upgrade files from CCO and converted them to a bootable DVD. It's not supported by Cisco, but until we start seeing 8.6 bootable disks, there is not a lot of choice. Why they don't just make the downloads bootable puzzles me.
