Clustering different types of MCS's

We have an old MCS7820 that we want to cluster with another MCS. We want to use a 7825 or 35 to take advantage of the 1U/2U rack mount. Has anyone clustered different MCS's? Are there any other concerns other than ensuring that we don't exceed the max number of phones of the 7820?

Also, all references we find to clustering show 3 CM's in the cluster. Can you cluster only 2 CM's? What are the drawbacks?

Thanks for helping

Re: Clustering different types of MCS's

yes you can cluster different MCS's and yes 2 MCS's can be configured as a cluster with one as publisher and one as subscriber. The drawback to using 2 instead of 3 are that the publisher takes on a more active role. If you had 3, the publisher could be only a worst case active role. It would not need to be actively processing calls unless both subscibers are down. But 2 is fine depending on as you mentioned, the number of phones suggested is not exceeded
