22.1 Planning Your Migration

Make sure your setup addresses the following requirements before you migrate DSfW.

22.1.1 Prerequisites

Before you proceed with the migration, review the details in Prerequisites. For a successful migration:

  • The source server and the target server must be in the same eDirectory tree.

  • Ensure that the time is synchronized between the source and the target server.

  • The source and target servers must be in the same subnet and gateway.

  • The target server must be a non-replica server in the eDirectory tree. To make the target server a non-replica server, select the OES Pre-migration Server option while installing OES 2018 SP3 on the target server.

  • The target server DNS entry must point to DSfW source server IP address.

  • Hostname of the target server should not be same as any other server in the DSfW tree.

22.1.2 What is Migrated

  • DSfW configuration data present in eDirectory.

  • Configuration files for DSfW services like kerberos, samba, xad, and rsync.

  • Non DSfW services like iPrint and NSS. Non DSfW services need to be migrated as per the migration procedure for a particular service.
