Upgrade Call Maneger from 4.2.3 to 7.1.5 or 8.6

Hello everybody!

I need some help. Hope you can advice me. I am going to upgrade de call manager from 4.2.3 version to either 7.1.5  or 8.6. I have some issues I need to know before go ahead:

-Regarding the licencing process. How are traslated the CCM DLU licenses to the current CUCM  licenses?

-The current call manager is running into a 7825MDC. Due to I need to upgrade the device number to up to 1500 I have to migrate the MCS as well. Thereby I have two options:

              

               Option 1: Deploy 7835MCS refurbished instead of the current 7825MCS and upgrade to 7.1.5 version

               Option 2: Migrate to a VMWare vSphere v.5 platform  (already in use)  and upgrade to 8.6

In terms of upgrading steps/issues wich of these two options is easier (or less complex).

Thank you

Miguel

Upgrade Call Maneger from 4.2.3 to 7.1.5 or 8.6

DMA will get the info and you can migrate your phones into DLUs with it, otherwise licensing (licensing@cisco.com) can assist on that matter.

There's no direct upgrade path from any Windows CCM to 8.6, you need to be in Linux first.

If you don't want a two hop upgrade then it's 7.1

7.X is not supported on VMware, 8.0(2) and above is.

If you want to go to 8.6 you need to upgrade to such version on MCS, backup and then restore on VM fresh install.

Upgrade Call Maneger from 4.2.3 to 7.1.5 or 8.6

Hi,

Regarding the upgrade path. I am concern about the chance of move back (7.1.5 to 4.2, for instance) if necessary. There are 2 servers (publisher and subscriber). Could I upgrade just in one of them and keep the second one with the previous version (in case I need to move back into the old version)?

Kind regards

Miguel

Hi Miguel,

You could take the current Sub out of service and use it to become your

"Migration" Pub if you wanted to be super safe and this would leave the

existing 4.2 Pub in place in case you needed to revert But with proper planning

this shouldn't be necessary.

This will be a very complex process which will need to be broken up into

a number of distinct steps

The fist step for the CUCM upgrade path will be to move from 4.x to 7.x so you can leverage

the DMA upgrade/files. So I would break this down to securing a perfect DMA

.tarball (work with TAC to correct ANY errors) then the 7.x upgrade......let things

get working for a bit before the 8.6 upgrade.

This doc has the required steps for this 4.x to 7.x upgrade;

Upgrading to Cisco Unified Communications Manager Release 7.1(2) from 4.x Releases

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/upgrade/7_1_2/upgrd712.html

First step will be to create the DMA files. These files will then be

used when you go to do your CUCM 7.1(x) build. The DMA (Data Migration Assistant) files will

allow you to move your data from the Windows 4.x build to the new Linux 7.x build.Here is the requisite info for DMA;

You will have to determine what version you current servers will support this is the "master" list for Server support;

You will need to work with Cisco either directly via your SE, a Partner or

PUT (product upgrade tool) to secure the DVD's and pay for the proper licenses

that will enable the Software feature License for your new version.

Check out this great doc from Saurabh for the refresh upgrade notes for the final step to 8.6.

This Refresh Upgrade will also apply to your CUCM 8.6 final step;

Have a read of the attached .ppt as it has some really good info

Best of luck!

Cheers!
