A community college district wants to migrate classic DMVPN spokes to SD-WAN Edges without a single cutover for every campus. Which migration approach best matches that goal?
Select an answer to reveal the explanation.
Short Explanation
Nobody upgrades every campus on the same Saturday unless they enjoy outages. Brownfield SD-WAN migrations move sites in waves so leftover DMVPN spokes keep working until their turn. Phased coexistence beats a district-wide flag day.
Full Explanation
Brownfield SD-WAN adoption typically stages Edge cutovers while legacy WAN technologies such as DMVPN continue for sites not yet migrated. That coexistence avoids a single failure domain and lets operators validate templates, certificates, and underlay colors per site. Removing hubs first or stripping encryption during migration introduces unnecessary risk unrelated to the SD-WAN target state.
