|Oracle Directory Server Enterprise Edition Upgrade and Migration Guide 11 g Release 1 (220.127.116.11.0)|
This section describes two alternative deployment scenarios and explains how to migrate in each case.
The sample deployment scenarios include:
In a multi-master replication (MMR) deployment, two Directory Server instances are installed on different hosts. It is possible to run the hosts on different operating systems, but in this scenario, both hosts are running on the same operating system.
Table 10-1 Component Distribution in a Multi-Master Replication Deployment
The migration process keeps on-demand password synchronization running continuously on the preferred master or on the secondary master.
Note - If both hosts are running on a Solaris operating system, then a third host running Windows 2000 with Active Directory is required for synchronization purposes only. (No components would be installed on the third host.)
The following figure illustrates the process for migrating Identity Synchronization for Windows in a MMR deployment.

Table 10-2 Multi-Host Deployment
In the previous scenario, hosts 1 and 2 are running on the same operating system.
Note - Directory Server at host1 contains the configuration registry and the Admin Server console. Ensure you migrate to Directory Server 11g Release 1 (18.104.22.168.0) using the -N option to keep the Admin Server intact. For more information on migrating configuration data and user data, see Using dsmig to Migrate Configuration Data and Using dsmig to Migrate User Data respectively.
Directory Server at host2 contains the data and the Directory Server plugin. When you migrate Directory Server to 11g Release 1 (22.214.171.124.0), the plugin configuration is lost. But it does not cause any problem as Identity Synchronization for Windows migration requires the connectors to be reinstalled and plugin to be reconfigured. Therefore, Directory Server at host2 should be migrated after Identity Synchronization for Windows uninstallation.
If both hosts are running a Solaris operating system, then a fourth host running Windows 2000 with Active Directory is required for synchronization purposes only. (No components would be installed on the fourth host.)
