[cisco-voip] Upgrading CUCM from 8.5 to 10.5

Fri Mar 27 11:39:58 EDT 2015

Adding to Neal’s comments, you might find the following documentation helpful:

Cisco Live: Best Practices for Migrating to CUCM 10.5

The first few sections in this doc might be helpful as well.

As Neal mentioned, you have to keep in mind that 10.5 is VM only and, while a direct RU upgrade from 8.5 to 10.5 is possible, you also need to consider the hardware requirements of 10.5 as well. Check out the 10.5 OVA specifications here:

http://www.cisco.com/web/software/283088407/112975/cucm.ova.README.txt

But to the steps mentioned below, this description sounds more like a Jump Upgrade procedure, which I understand is only required when upgrading from CUCM 6.x/7.1(5), not CUCM 8.5.

So for the 8.5 to 10.5 upgrade – It seems the most straight forward method, assuming you’re on an MCS server, would be to

1)      DRS restore your 8.5 cluster to a virtualized environment built out on a v8.5 OVA template.

++ I’ve read that 8.5 won’t install on a v10 OVA template. Have I tried this myself? No. Should easy enough to test though. If it doesn’t, I’d imagine it’s due to disk sizing requirements for the user node specs.

2)      Use LCU to gather your license information pre-upgrade

3)      Refresh Upgrade from virtual 8.5 on UCS directly to 10.5 manually without PCD – requires the keys.cop and refresh_upgrade files. Last I checked you cannot upgrade from 8.5 to 10.5 via PCD.

++ I’d suggest reviewing the v10 OVA readme file and make sure you’re virtual machine specs and reservations are sufficient for the upgrade. Update if necessary – careful with disk resizing – there’s a recent thread on this topic alone.

4)      Submit a license request gathered from PLM – you’ll have a 60 day grace period.

++ At this point you should be on 10.5 with proper CPU and memory specifications and reservations, but your virtual disks will still be the 8.5 provisioned specs. Having 2x80GB drives on CUCM 10.5 is supported and it runs just fine.

My suggestion would be to review all the migration and upgrade documentation you can find and review it. This might also help:

MCS to UCS – Slides 70 and higher might be most helpful:

Also keep in mind that live MOH audio sources via USB are not supported in 10.5 – you’ll need an alternate, IOS based solution for this.

Another caveat to keep in mind is Unity Connection and AXL synchronization – this will break unless you’re on Unity Connection 8.6 SU5 or a higher ES. If you patch to 8.6SU5 then be aware of CSCuq63776 – it’s pretty critical and you’re pretty much guaranteed to hit this after a SU5 patch. The latest CUC ES is 163 and includes a fix for this defect in addition to the BASH vulnerability patch and the fix for AXL.

I hope someone corrects any mistakes I made above and hope this helps.

10.5 is VM only, 8.6.1 usually was MCS hardware.

To upgrade you will need to 8.6.1 upgrade to 9.1 on MCS. Then 9.1 MCS to VM, the upgrade 9.1 to 10.5(2)SU1.

Supported vs the system will upgrade are two different things.

Hi All

Just checking through documentation for CUCM 10.5 for an upgrade, the compatibility guide states that a direct upgrade is from 8.6.1 onwards as shown below.

However in the Read Me notes for 10.5.2 Su1 it states the following

Version and Description

This SU is a cumulative update that incorporates all of the fixes and changes from Cisco Unified Communications Manager 10.5(2) along with additional changes that are specific to this SU.

Note

You can only install this SU on Cisco Unified Communications Manager Release 6.1(4x), 6.1(5x), 7.1(3x), 7.1(5x), 8.0(x), 8.5(1x), 8.6(x), 9.0(x), 9.1(x), 10.0(1), 10.5(1), or 10.5(2) This SU will not install over any 10.5(2)ES’s. Upgrades from 6x, 7x, 8.x, and 9.x need to be requested via PUT (www.cisco.com/upgrade<http://www.cisco.com/upgrade>) to obtain the necessary license. This SU should not be installed on a Business Edition 3000 server.

I would normally always go with what is says in the compatibility matrix, however my colleague has just done an upgrade albeit in a lab from 8.5.1 direct to 10.5.2 SU1.

Anyone know if he just got lucky or if that is now supported?

Regards

Nick
