This topic covers the WAN Gateway role, replication actions, and updates in PingDirectory Servers mixed version environments.
Consider the following when using the WAN Gateway role in mixed-version environments:
- WAN Gateway Role assignment is only available on PingDirectory Servers version 3.5 and later.
- Legacy servers earlier than 3.5, are never selected as WAN Gateways.
- Updates from legacy replication servers forward to all replication servers and do not funnel to a single WAN Gateway, which increases WAN during replication.
- Updates from remote WAN Gateways forward to the legacy replication servers, which increases WAN traffic during replication.
