[cisco-voip] Unity Connection upgrade from 7.1(3) to 9.1(2)

Thu Apr 23 08:59:38 EDT 2015

Its also possible to do this without COBRAS or DRS.

Basically you just replace each node one at a time on the current 
version but running on the new HW.

Once you have the current version running on the new hardware you 
upgrade as usual. (Don't forget to get your 7.x licenses ahead of time 
for the new HW)

Its possible that you will encounter a bug in 7.x when doing this that 
will prevent you from adding new users.  There are Informix commands 
that are run to resolve this (just be sure to test that you can add new 
users).  I believe root access (or TAC) is required to correct this.  At 
one time the instructions were published on CCO.

This provides a seamless upgrade as there is always a CUC node in 
service that can answer calls and large message stores don't have to be 
manually migrated (they are migrated as part of the initial install from 
the production node).

I can probably did up some generic almost step by step instructions and 
the fix for the creating new users if this is something you are 
interested in.

Its also possible to do this direct to VM, though you will need root 
access (only to change license mac to from virtual MAC to physical) and 
won't have TAC support while running 7.x on VM.  Also, once you reach 
9.x your partitions will be unaligned and a 9x VM to 9x VM migration 
would be required to correct this.

Not saying this is the right option in your case, but it does work.
