[cisco-voip] Migrating from CUCM 7.1.3 to CUCM 8.6.2

[Fred Hunt]

Thanks Stephen and Ryan.  I have attended some of the CUG webinars on upgrading to 9.  I figured that I would avoid the licensing changes by only going to 8.6.2.  We are a small organization (under 300 users) and my primary motivation for upgrading is to remain on a supported version.  I'll read up more on moving to version 9 instead.

Jump to 9.1(2) is where you want to be.

Hi Fred,

Although you mention 8.6.2, Cisco have a big promotion called "Drive to 9" that you should take a close look at (if not already), in particular they have numerous upgrade options in particular some direct methods (jump) and tools that can simplify the whole experience.

Have a look at the community page:

https://communities.cisco.com/community/technology/collaboration/uc/migration

The following video gives you a good overview CUCM upgrade procedures:

Also,
Cisco's own Akhil Behl (author of "Securing Cisco IP Telephony") and myself are hosting a series of webinars on Endpoint Security and Compliance. We shall be sharing some information that will relate to your upgrade, so if you have the time register for the session(s), details below.

Thanks

I'm interested in migrating to CUCM 8.6.2 running on VMs considering that 7.1.x is getting closer to the end of support.  I've been working to determine the appropriate process to follow, but have a question that is not addressed in the documentation that I reviewed.  Both of our current servers are model 7835-H2, which is only supported for use in a bridge upgrade, not for production use.  The system requirements for 8.6.x call for 4 GB RAM and 146 GB disks.  Our servers currently have 2 GB RAM and 72 GB disks.  Will I be able to use these servers for the bridge upgrade even though they don't meet these requirements?
Thanks for any input.
