We need to upgrade CUCM in the Unified CCE (ICM 8.5.2, CVP 8.5.1). Current version is CUCM 7.0.2 and wants to upgrade CUCM 8.6.2 (both pub and sub). From the Unified CCE software compatibility matrix we have found that upgrade path is 7.0.2••>7.1.3••>8.6.2. Can you suggest us …

  • •1.       Upgrade procedure
  • •2.       License issue
  • •3.       Database issue
  • •4.       Configuration/database backup issue
  • •5.       Media

Muhammad,

Rob gives some excellent advice there. We recently did a 7.1.3 to 8.5 upgrade

7.1.3 was on MCS servers, the 8.5 had to go on virtuals servers (we put then on C-Class chassis)

But essential what we did (or should I say the partner we worked with) was take a DRS of the current system, build the new system on another set of MCS servers (you may need to get you Cisco partner to assist with licensing).

So built it to 7.1.3 first restored the DRS and then  upgraded 7.1.3 to 8.5 on the MSC servers. Now when you do this the software will load bu the services wont start. Not an issue

We installed 8.5 on the C-Class chassis, took a DRS from the MCS servers with 8.5 on then and restored it on the virtual images (again you will need assistance from Cisco licensing)

And that was it. Just remember to restart all the services.

Prior to the actaully switching we also upgraded all the phones (over 4000) over a number of weeks prior to the upgrade switch to the latest versions of phone firmware and ensured this was installed on the new servers. Meant we didnt have 4000 phones trying to upgrade at once expecially when 3000 are over the WAN links

hope thisgive you an idea of how it can be achieved with little issue...Good planning and a good Cisco partner is key.

thanks

Hi Muhammad,

The upgrade from 7.1(3) to 8.6(2a) is a direct upgrade path as shown;

Check out Table 4:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/compat/ccmcompmatr1.pdf

The move from 7.1(3) to 8.6 does incorporate a new "Refresh" upgrade portion (see below)

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

Supported Cisco Unified Communications Manager Releases by Server

http://www.cisco.com/en/US/prod/collateral/voicesw/ps6790/ps5748/ps378/prod_brochure0900aecd8062a4f9.html

If your current servers don't support CUCM they may support a "Bridge" upgrade;

Bridge Upgrade - just in case

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/cucos/8_6_1/cucos/iptpch7.html#wp1119088

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;

And read great the attachments from Ryan

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.

You may want to upgrade the current phone firmware ahead of time to match the CUCM 8.6

versions

Check Table 33 here.
