Hi Malik,

Hope you're doing well. Please take a look at another recent post where I had provided all relevant links for a migration such as yours:

Note: Please review the compatibility matrix I provided to see the upgrade path from 5.1 to 8.5.

Dear Amit,

Thanks a lot. I have reviwed your thread.

As long as hardware compatability is concerned MCS 7825-H3 can be upgraded to 8.5

Can you please just gudie me for the best possible path for the upgrade from 5.1 to 8.5

Regards

Malik

Hi Malik,

Here are some key points to keep in mind:

1>     As per software compatibility matrix:

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

There is no direct upgrade from 5.1 to 8.5. You would need to upgrade to a minimum of 6.1(4) first, followed by an upgrade to 8.5(1).

2>     Remember to take DRS backups prior to every upgrade i.e. before upgrade to 6.1 and before upgrade to 8.5. Also, take a backup of 8.5.

3>     Do a fresh install of CUCM 8.5 (same version and build as currently installed on your MCS server) onto the UCS platform.

4>     Apply for licenses for MAC address in output "show status" of the Publisher of the newly installed 8.5 on UCS.

5>     Restore the DRS backup taken from MCS cluster onto the UCS platform.

HTH.
