Cisco Unity Express : Upgrade from 2.1 to 8.0

[csshenoy80]

Hi

We have a Cisco 3845 with AIM-CUE version 2.1. We are planning to upgrade the CUE to 8.0, to work with Cisco CUCM 8.5. As per compatibility matrix, the steps would need to upgrade the CUE through multiple stages to get it to 8.0. The licenses as well need to be migrated to reach the 8.0 version.

Can the AIM-CUE be upgraded to 8.0 or is a new module required?

Thanks.

You can only go as far a 7.X on AIM-CUE

CUE 7.3 is compatible with CUCM 8.5, so this solves the requirement. Also, believe the licenses can be migrated accordingly.

thank you for the response.

I'm not sure why someone has low rated the post above by Java, that is 100% correct, and made to help.

To partially balance the mistake, I have rated for what is worth: 5 stars.

Marwan,

I am almost sure that you will have to follow that longer path only. You can confirm the same by referring to CUE 7.0 release notes guide & then you will find the lowest possible version from which the upgrade is allowed. In this case mostly it will be 3.x. Then again refer CUE 3.x's release notes guide & you will realize that 2.x is the lowest possible version from which an upgrade to 3.x is possible. Thus you will drill down to your present version & chalk down the upgrade path, which is mostly 2.1 --> 2.2 --> 3 --> 7.0.

Hope it helps ?
