I am in the process of migrating from Exchange 5.5 to Exchange 2003 for my Unity message store. I've already set up the Exchange 2003 server as a mail server so that I could work out any Active Directory Connector issues. I am referring to the Reconfiguration and Upgrade guide, and then subsequently to the Recommended Service Packs and Upgrades document. While reviewing the Service Packs and Upgrades Doc I found this warning:
Caution Note that if you are using Cisco Unity 4.0(3), you must run the Cisco Unity Permissions wizard before you install Exchange Server 2003 Service Pack 1 or later. Otherwise Cisco Unity will not function properly. You must use the Permissions wizard version that is included with Cisco Unity 4.0(4) (on DVD 1 and CD 1). The same version is also posted on the Cisco Unity Tools website at http://ciscounitytools.com/App_PW_403.htm. For information on running the Cisco Unity Permissions wizard, refer to Permissions wizard Help.
Well, unfortunately I am running 4.0(3)SR1 and I've already applied SP2 to the Exchange 2003 server but I have not yet done any of the Unity integration steps. So can I still work with this box, or do I need to start Exchange from scratch so I can run the permissions wizard before installing SP2? Should I update Unity to 4.0(4) or better before integrating the Exchange 2003 server?
