1.3 Migration Scenarios
The Migration Tool supports the following scenarios:
1.3.1 Consolidate
The Consolidate scenario helps you reorganize your network by copying the service configuration and data from any number of source servers to the target server. By consolidating data onto newer, more powerful servers, you can simplify your network administration processes and lower your IT costs.
This section describes example scenarios of how to consolidate your data.
NetWare-to-OES 2 SP2 Linux Consolidations
For NetWare-to-OES 2 SP2 Linux consolidations, the service configuration and data from the source servers is copied to the target server.
Example Consolidation Scenarios
The benefits of the Migration Tool can be better understood through examining some sample consolidation scenarios.
Basic Server Consolidation: Many-to-One
In the first scenario (see Figure 1-1), suppose you have three existing NetWare servers. You recently purchased a multiprocessor server and installed OES 2 SP2 Linux. You want to copy the data from each of the three servers to the single OES 2 SP2 server. Rather than manually moving all the data, or backing up the data on each of the three servers and then restoring it to the OES 2 SP2 Linux server, you can use the Migration Tool to automate the process.
Figure 1-1 Many-to-One Server Consolidation
Although Figure 1-1 shows the servers all in the same eDirectory tree, the Migration Tool lets you perform tree-to-tree consolidations as well.
Consolidating Data from Multiple Servers onto a Two-Node Cluster
In the second scenario (see Figure 1-2), suppose you have five existing OES servers. You recently purchased two multiprocessor servers and the necessary hardware to create a two-node cluster complete with an attached Storage Area Network (SAN). You have decided to install OES 2 SP2 on the two-node cluster. You want to copy the data from each of the five servers to the SAN on the two-node cluster. Rather than manually moving all the data and Printer Agents or backing up the data and restoring it to the SAN, you can use the Migration Tool, which automates the data migration process.

Cross-Platform Data Consolidations
The Migration Tool supports cross-platform data consolidations from NetWare, OES 1 Linux or OES 2 Linux, OES 2 SP1 Linux servers to OES 2 SP2 Linux server.
You must use the Migrate Windows Share Utility to copy data from Windows servers in a Windows* NT* domain or Windows 2000/2003 mixed mode domain to OES 2 SP2 Linux servers.
1.3.2 Transfer ID
Transfer ID is a migration scenario for transferring the server identity of the source server to the target server. The identity of the server is made up of its IP address, hostname, eDirectory identity, NICI keys, and the certificates from the source server.
On successful completion of the Transfer ID migration, the target server functions with the identity of the source server and source server goes offline.
