[cisco-voip] CUCM upgrade from 10.5 to 11.5

[Lelio Fulgenzi]

I wonder if there are additional services you could subscribe to. Front it with VPN/IP extension service so the vSwitch can be configured with any VLAN that the extra layer offers.

From what I understand, you cannot extend your IP, it's IP's assigned from AWS.  At least for public facing.  I'm assuming you can spin up another vswitch on the vsphere side and have private IP's, just like we can locally.

Hmmm, in actuality, VMware on AWS seems like it will be the best replacement for a physical stack of bare metal servers for temporary use. As long as the IP address space was the same, you could simply shut them down and export after the migration was complete.

Side question…

Anyone know how that works? Can you extend your IP address space into AWS without much effort?

If you are one of my customers, I can arrange that.  Do we have a web page where you can just go sign up, no.  But there are services that let you rent bare metal servers.

VMware and AWS are teaming up to rent you vsphere on AWS bare metal.

This should be a signal to professional services orgs out there to rent out UCS systems for offline upgrades. :)

Agree with Lelio but sometimes parallel upgrade are just not possible.

I’ve done 3 x 10.5 to 11.6 direct upgrade recently any only had one issue that wasn’t directly related to the upgrade. Other than that they have been pretty smooth.

In your pre-checks don’t just check DB replication but also CUC and UCCX replication on the respective servers (utils uccx/cuc dbreplication status). Plus check from the pub and sub as on a CUC upgrade recently it kept failing, Turned out CUC replication wasn’t set up correctly. Ran the command from the Pub and it stated everything was good, Ran from the Sub said it was failed. Ended up re-building the CUC Sub. The issue came about from a host name change years back and some of the tables where not updated on the sub.

Also double check the memory requirements. As 11.x requires 2 extra gig most of the OVA’s.

Upgrade timings going from 10.5 to 11.5/6

Memory upgrade where completed prior to upgrades.

CUCM Upgrade Pub 90 Mins 7.5k OVA
CUCM Upgrade Subs 60 Mins
IM&P Upgrade Pub 70 Mins 5K OVA
IM&P Upgrade Sub 50 Mins

CUCM Switch Versions Pub 40 Mins
CUCM Switch Versions Subs 30 Mins
IM&P Switch Versions Pub 30 Mins
IM&P Switch Versions Sub 30 Mins

UCCX Upgrade Pub 80 Mins – 300 Agent OVA
UCCX Upgrade Sub 60 Mins
UCCX Switch Versions Pub 45 Mins
UCCX Switch Versions Sub 30 Mins

I will say one thing, if you have the opportunity to duplicate the environment in an off-line network and perform the upgrades there, then your migration will basically be downtime involved with shutting down old servers and turning up new servers. This is not trivial, by any stretch of the imagination. However, once you put some thought into it, I think you’ll find this method extremely valuable.

You work out all the kinks in the offline network and repeat until you are satisfied.

You’ll need a couple of things to make this work, namely, a change freeze window and the “pre 8.0” enterprise parameter.

We’ve done this twice now and it’s worked like a charm.

I would hate to do upgrades on live systems.
