Normal OpenEdge RDBMS database rules apply if the Schema Holder does not contain newer features or functionality that are not supported by the lesser release being used by the client.

For example, OpenEdge 11.4 and 11.3 clients can connect to an OpenEdge 11.4-created schema holder being served in multi-user mode by an OpenEdge 11.4 RDBMS broker. However, if you update the 11.3 schema holder using OpenEdge 11.4 and enable new features, then the OpenEdge 11.3 client will no longer be supported, and you might experience runtime errors.
