Integrating OSDP Readers with Legacy Access Controllers

Legacy systems can still support modern lanes if integration is staged correctly.

Approach:

1. Map each panel's protocol and capacity constraints.
2. Use protocol converters where full upgrades are not immediate.
3. Segment pilot lanes for controlled rollout.
4. Establish a cutover playbook with rollback safeguards.

This avoids full rip-and-replace while still raising security posture.
