Interaction between Replication Servers of different versions is restricted to the capabilities of the oldest version.
Information associated with new features may not be available to Replication Servers of earlier versions. See the documentation for each feature introduced in a new version, such as function-string inheritance or multiple replication definitions, for additional information about usage restrictions in mixed-version environments.
Refer to the installation and configuration guides and the release bulletin for your platform for more information about mixed-version systems and about setting the site version and system version.
