Re: Unity 4.2(1) schema backward compatible with earlier version
Hey Scott -
We were running version 4.0(5) in production when we applied the 4.2 schema updates. No problem with doing this. The schema extensions account for new/future functionality but does not impact current Unity functionality. 4.1 and 4.2 Unity servers can run together in the same AD forest. There is a caveat with digital networking and discontinued support of Exchange 5.5 - "Beginning with Cisco Unity 4.2(1), we no longer support using Exchange 5.5 as a message store for Cisco Unity voice messages or as a partner Exchange server. If you are using Digital Networking to connect a Cisco Unity 4.2(1) server with a server running an earlier version of Cisco Unity, in order for Digital Networking to continue to work for all Cisco Unity servers, you must upgrade or change the partner Exchange server for each Cisco Unity server to an Exchange 2003 or Exchange 2000 server.".
