[cisco-voip] Unity 4.x to 7.x with failover upgrade

[Voice Noob]

I do not plan to go to 4.1.2 for Unity first. All of my upgrades have been
from 4.0(5) directly to 5.0. I am not going to use COBRAS for this upgrade,
It does not get everything and I am very comfortable with the upgrade
process for Unity. I just have not done a unity failover upgrade.

I'll be researching this myself next week and be doing some lab work to
test.  I have similar scenario in end of January.  

 

I plan to upgrade from Unity Unified Messaging (with Exchange) 4.0.5 to
4.1.2  then;

 

a)      New hardware install 4.1.2 and DIRT restore from old hardware, then
upgrade to 5.0.1 (they plan to use Exchange 2007 cluster)  I have done this
before but without failover

 

or 

 

b)      New Hardware install 5.0.1 (they plan to use Exchange 2007 cluster)
and use COBRAS to move subscribers/call handlers from old 4.1.2 box (this is
new I haven't tried this yet)

 

I understand there are issues with DiRT and 4.0.5X thus the 4.1.2 upgrade.

 

My customer is not using Viewmail for Outlook so I don't have to worry about
pushing that out.

I am getting ready to do an upgrade from Unity 4.x to 7.x with failover in a
UM setup. I have not done a failover upgrade but I have done several Unity
upgrades in both VM and UM. I will usually  take a DIRT backup of the
customer Unity server, upgrade it in VMware to the version I want to go to.
Do a new DIRT and then restore it to the new server hardware. I have done
this before in a UM setup and it can be done but there are a few exchange
issues you have to deal with. I am not concerned with those and I can work
through them. My question is do I need to upgrade the failover server? Can I
just upgrade the primary and once it is up and working with version 7 do a
fresh install of the secondary server? Do the changes from the primary Unity
server replicate over to the secondary like call manager PUB and SUB? Thanks
for any help.
