Reasons for Installing a New Directory Server

You might need to move your Directory Server and, thus, to migrate your Messaging Server configuration data, in the following situations:

• You want to upgrade Directory Server.

  You might be upgrading Directory Server from one version to another—for example, from iPlanet Directory Server 5.x to Sun Java System Directory Server 6.x.

• You want to replace the original Directory Server host machine with a new machine.

  You might reinstall Directory Server on a new host–without necessarily upgrading the software—when you need to modify the topology of your entire deployment. For example, you may be enlarging your deployment to encompass multiple hosts, and need to point Messaging Server to a new Directory Server host.

  Or you may need to move Directory Server from one machine to another because you are upgrading hardware.
