Hi,
I am about to add a CM cluster(Combined Multiple Site model)to a Centralized (multiple-site) model.
HQ CM cluster is running 6.1(2) with plan to upgrade to 6.1(3).
Can I install 6.1(3) on the new CM cluster (remote branch) and still be able to InterCluster trunk between them as well as provide redundency and load balancing.
Thanks in advance

You can definitely have an ICT between different CM versions. Not sure what you mean by redundancy and load balancing. This is not usually done between clusters.

Generally, redundancy and load balancing are done within a cluster and not between clusters. If you are looking for these features and need the two to talk to each other (hence the ICT), you may want to look at having a single cluster with subscriber servers at the branches (Clustering over the WAN). There are some minimum requirements to meet in this scenario such as network delay, etc., but if you meet those it might be a good option for you.
Hope this helps.

Cool, Thanks Brandon
I don't think I am sure what I mean.8-)
Load Balance (Remote branch where new cluster is going will cover the Geo region (other remote branches) of phones)
Redundancy (If 1 cluster goes down, we will not lose entire call processing)
Thanks Again!!

We talked about that senerio. Can you please provide the URL or important information in regards to minimum requirements for this senerio.
Thanks Brandon!
