UIpgrade path options for 5.1.x

Unanswered Question
Dec 20th, 2007

I`ve seen the upgrade path doc showing the path for 3.x, 4.x , 5.x upgrading to 6.x. It shows you can upgrade from 5.1.x to 6.x but I`m also aware that you can not go from 5.1.3 to 6.x . We are currently running 5.12.a and have to upgrade to either 5.1.2b or 5.1.3. but my concern is if we chose 5.1.2b can we still go to 6.x ? or is it just 5.1.1.3 which can not go 6.x

I have this problem too.

Hi Wayne,

This restriction does not apply to CCM 5.1.2b (as it does to CCM 5.1.3) :)

Here is the CCM 5.1.3 note;

Do Not Upgrade from Cisco Unified CallManager 5.1(3) to Cisco Unified Communications Manager 6.x

It is not possible to successfully upgrade from Cisco Unified CallManager Release 5.1(3) to Cisco Unified Communications Manager Release 6.x.

Hope this helps and Happy Holidays!
