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

Mon Aug 19 13:29:06 EDT 2013

Hah,

As a 6.1 user trying to go to 9.x this is an all too accurate statement
of how Cisco does their licensing.  Don't forget the different flavor of
user licenses too, basic, enhanced, cuwl, etc.  Oh, you work in a shift
environment with mobility login?  Have fun figuring that out when it's
not a 1:1 phone:user ratio.

Even with 8.6, you'd have licensing changes. With 8.6, it is licensed
based on subscription of users, not DLUs. Except the catch is that even
though it is licensed based on users, the software itself still uses
DLUs. When you buy a user, you get a license file with a corresponding
number of DLUs in it. Nobody at Cisco can tell you what that number is,
and if you try to get any help related to your DLU counts, they'll just
get confused and incorrectly tell you that you're out to lunch because
8.6 doesn't use DLUs and is licensed based on users. Totally asinine
that it's licensed based on one system, but the software itself enforces
licenses based on a totally different system. The licensing for 8.6 is a
gongshow because the Cisco people only understand user-based, the
software only understands DLU-based, and there's no documentation
reconciling the two.

With 9, even though you still have all the headache of changing
licensing systems, at least you end up with only a single licensing
system in the end. So there is less opportunity for cluelessness and
confusion.

Based on past experience, Cisco will probably completely re-engineer all
their licensing very soon anyway, since it's almost getting to the point
of being understandable, which they seem to be against. :-\

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:

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.
