I have a CCM 4.1(3) pub/sub cluster. This cluster services a main office with about 450 users, in which it is connected locally. It also services 6 other smaller office with between 20-50 people each.
I have a data center that is about 50 miles away from the main office connected by 20Mb/s fiber. Each office has a full T1 to both the main office, and the data center. I would like to move one of these CCM's to the data center for HA, in the event that the main office went offline for some reason.
1 - Which do I move? I would think the Pub/Secondary should move so that the main office w/450 users still utilizes the Sub/Primary locally.
2 - The connection between the data center and main office is Layer3, so the IP address of the one that moves will need to change. Is this possible with CCM?
Thanks for the help.
