This module provides an overview of migrating to the new messaging server from Sun IMS 4.0 or Netscape MS 4.x. You can skip this section if you are not interested in migration. This does not give specific commands needed to fulfill the migration. Please refer to the online Install Guide if you need specific commands/steps. If you are upgrading from a previous version of the iPlanet^TM Messaging Server to version 5.2, then view Appendix C of the Installation Guide. Before getting into the migration overview, here are the prerequisites:

Migration Prerequisites

These migration procedures and scenarios assume the following prerequisites:

• The system to be migrated from is a SIMS 4.0 or Netscape Messaging Server 4.x system.
• The LDAP directory used with the system is the Netscape Directory Server 4.12.
• The Netscape Messaging Server system uses UIDs of the form local_part or local_part@FQDM. (See "Netscape Messaging Server 4.x Directory Namespace Limitations".)

Migration Toolkit

The migration toolkit is required for the procedures described in this book. It consists of the following:

• Schema files that provide multi-schema support during migration.
• imsdirmig command that converts directory entries to use the iPlanet Messaging Server schema. This command runs on all iPlanet Messaging Server supported platforms.
• imsdaaci command that creates an LDIF file to support iPlanet Delegated Administrator for Messaging. This command runs on all iPlanet Messaging Server supported platforms.

Migration Process

The migration method you choose depends upon three parameters.

• Whether you are migrating a system from SIMS or the Netscape Messaging Server.
• The complexity of the mail system (whether the system operates on a single-standalone system, or consists of numerous systems fulfilling different functions and acting in concert together).
• Tolerance of downtime (that is how long customers can go without sending or receiving mail).

Below are the topics covered in this module:

• SIMS 4.0 to iMS 5.2
• NMS 4.x to iMS 5.2

Target Skills

After completing this module you should be able to:

• Describe the migration overview of moving from SIMS 4.0 to iMS 5.2.
• Describe the migration overview of moving from NMS 4.x to iMS 5.2.
