Install a new 4.x Directory Server as described in Chapter 2, "Using Express and Typical Install,", Chapter 3, "Using Custom Install," or Chapter 4, "Silent Installation." Do not use the same port number your production server uses (e.g. port 389) because this initial directory will be used for server registration purposes only.
Shutdown your old Directory Server (this will automatically be done for you if the server is not shut down when you begin migration).
Start the Netscape Console using an account that has full read access to the server root.
In the Netscape Console's navigation tree, select the Server Group folder for the host on which the migration is occurring.
In the Object menu, select "Migrate Server Config..."
Enter the full path to the old server's installation root directory. For example:
/usr/ns-home
Select the old server to migrate from the resulting list.
Select Yes to overwrite any existing SIE data.
Select the new server to migrate the old directory data to. Select "Create New Instance" to create a new instance to hold the data.
Enter the Root DN password. This will be used for your Directory Server 4.x directory manager password.
