Hi I'm running a CCM 4.0 with a sub/pub in a single cluser. Servers are at End of Sale. Looking to upgrade to 5.1. What would I be losing if I went to a Single Server with RAID redudacy and adandon the Pub/Sub Configuration?? Keep in mind I want an upgade which will last for at least a couple of years, and it will be involved in a Unified Messaging enviroment.
Thanks in advance
