Through this video, I'll show you how to upgrade a CUCM/CUPS 8.6 to CUCM/IM&P 11.0
This video is no replacement for reading the documentation on the upgrade, and also the Release Notes for the product. This is only meant to be a visual guide of how the procedure will look like, so you can have a reference for the time when you do this.
The 3 documents you NEED to read, are: A) Compatibility matrix B) Upgrade guide C) Release Notes
Those will contain ALL the information you would need
One additional consideration, in case you have EM, you need to stop/disable the service prior to the upgrade, this requirement has been removed in the new releases, but, you still need to do it for this scenario, or if using previous version.
There are other COP files you might have heard about: ciscocm.refresh_upgrade_v1.5.cop.sgn This one is ONLY required if upgrading from version 8.5(x), or earlier, to version 8.6(2), or later. Not applicable for this scenario.
ciscocm.free_common_space_v1.3.k3.cop.sgn This one is only used if you want to remove files from the common space partition, the CAVEAT, is that by running this file, you lose the ability to switch back to the previous CUCM release.
