Techniques are provided herein for staged migration to Ethernet Virtual Private Network (EVPN) Flexible Cross-Connect (FXC) / Virtual Private Wire Service (VPWS) on a site-by-site basis and per Peer-to-Peer (P2P) instance. This will enable staged migration without requiring any changes to existing legacy VPWS. These techniques should thereby allow for the coexistence of Provider Edge (PE) devices running EVPN FXC/VPWS and legacy VPWS. Furthermore, migration may occur from legacy/old device to new device P2P services.
