CUCM 7.1 to 8.6 with Unity 4 - Question.

[Juan Gerardo Hernandez]

Hi all.

I am going to migrate from call manger 7.1.3 to 8.6.1, I already migrated de database to 8.6 and I wanted to know if in the moment to migrate, cisco Unity 4 would be registered on 8.6 as in my 7.1

If the answer is no

Can you please advise me to solve this, maybe a SIP Trunk, or another way to make that System work.

Reggards, and Thanks for your replies

CUCM 8.6 per the following matrix requries Unity 5.0 or newer for SCCP integration:

For SIP trunk compatibility you also need to go to version 5.0

At this point since Unity is a dead product I would strongly suggest you look into migrating to Unity Connection.

HTH,

Chris

Not correct answer, but it was helpful.

I migrated my Call Managers to version 8.6, and Voice ports for Unity 4.0 Still registering, even still working, I think there is a missunderstanding between not "supported" and "not working".

However y migrate user accounts to unity 7.

Sure, it would register, but it would not supported by Cisco including Cisco TAC, so if you ran into issues they would not assist. Since the TAPI was not tested against that version who knows what issues you would encounter.

Since you migrated to version 7, all should be good. Make sure you upgrade TAPI after upgrading CUCM.

HTH,
