After you have upgraded the current Replication Server and set its site version to the current release, the Replication Manager route upgrade feature copies the replication definitions with Java columns from upstream Replication Servers to the current Replication Server.
Although Replication Server does not propagate replication definitions with Java columns to pre-12.0 version Replication Servers, you can replicate Java columns to older Replication Servers by manipulating function strings. See “Using function strings to replicate Java columns to older Replication Servers” for more information.
