EMCC between CUCM 10.5.2 and 8.5

[Marco Villani]

Hello,

my customer has three clusters, APAC-EMEA-NA. We are in the process of upgrading all three to 10.5 . So far only NA is on 10.5.2, EMEA and APAC are still on 8.5, also all three have different domain names.  I need to rebuilt the EMCC between the NA and the remaining of the clusters and although the Cisco Matrix says its supported, i'm looking for anybody who has experience with a similar setup and gotchas. any feedback positive or negative is greatly appreciated.

Thank You in advance.

Hi Marco,

As long as EMCC is set up as per Features and Services Guide there should be no issues with the setup. For any restrictions with EMCC you can always refer the Restrictions section of EMCC in the Cucm Features and Services Guide.
