Migrating from SMTP Networking to VPIM

Networking

Overview

This chapter provides information on migrating from SMTP Networking to VPIM Networking for messaging between Cisco Unity servers that access different directories. Because Cisco Unity 4.x was the last train that supported the SMTP Networking option, customers who need to network Cisco Unity servers that access separate directories must migrate to VPIM Networking instead of using SMTP Networking after upgrading to Cisco Unity 5.0 or later.

Both SMTP Networking and VPIM Networking use SMTP as the mechanism for exchanging messages, but the message format differs. SMTP Networking uses a proprietary message format, while the message format in VPIM Networking adheres to the VPIM industry standard. In addition, VPIM Networking provides functionality that is not available in SMTP Networking. See the “VPIM Networking” chapter for more information.

Prerequisites

Before starting the migration, verify that the following prerequisites have been met:

•The servers have already been upgraded to Cisco Unity 5.x as described in the Reconfiguration and Upgrade Guide for Cisco Unity Release 5.x (With Microsoft Exchange), which is available at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

•A license file with a VPIM license has been obtained and installed on the Cisco Unity Bridgehead server.

•Cisco Unity and Exchange meet the requirements as described in the “VPIM Networking Requirements” section in Networking Options Requirements for Cisco Unity, at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.
