After the initial synchronization is complete, you can tell the PingDataSync server to begin real-time synchronization for the sync pipe, at which point it will start watching the source for changes and making a corresponding set of updates to the destination server.
You can do this using the realtime-sync start command:
realtime-sync start \
--hostname sync.example.com \
--port 636 \
--useSSL \
--trustStorePath config/truststore \
--bindDN "cn=Directory Manager" \
--bindPasswordFile directory-manager-password.txt \
--pipe-name "LDAP Source to SCIMv2 Destination" \
--no-prompt
