I’m currently in the process of planning an upgrade from v9.6 to v10.1. We have 2 clustered backend IS’s, an unclustered Broker that I’d like to upgrade to Active/Active UM, 2 clustered TN IS’s and 2 MWS. What I’d like to know is what is the recommended upgrade path we should follow ?? Do we migrate the IS’s and MWS, then the Broker to UM ? Do I install Command Central before or after IS upgrade ? Do I migrate Broker to UM before or after IS upgrade ?
