You probably have a network that is already providing services to network users. In many cases, the services you are currently running will influence your approach to implementing OES. In some cases, there are specific paths to follow so that the OES integration process is as smooth as possible.
Novell has invested considerable effort in identifying service coexistence and migration issues you might face. We understand, however, that we can’t anticipate every combination of services that you might have. Therefore, we intend to continue developing coexistence and migration information.
For information about coexistence of OES 2015 SP1 servers with existing NetWare and Linux networks, see Section 8.0, Migrating Existing Servers and Data.
