what is the step by step process/procedure to follow of upgrading the Exchanger server 2010 sp2 to sp3?
My Environment: All servers are Entreprise Edition
Production:- HUB/CAS roles on same VM machine --- 2 servers
2 MBX servers physical
DR : 1 physical server holding 3 roles (HUB,CAS,MBX)
NO Edge, No unified roles.
