Playbook cover — six pages of legacy BAS migration guidance for facility managers, engineers, and general contractors.
What’s inside
- The Migration Map — legacy platforms and their upgrade paths (Andover Continuum, TAC Xenta, I/A Series, TAC Vista, LonWorks, pneumatic)
- Head-end migrations — swap the workstation without swapping the field devices, and where that approach breaks down
- Pneumatic-to-DDC conversions — how to phase out air-driven controls without gutting the mechanical rooms
- Twisted-pair migration options — Schneider SpaceLogic TPA-E and open T1L, side by side, with the wiring rules that determine which fits
- The phased pathway — what to migrate first, second, third, and why the sequence matters more than the speed
- Real budget numbers — construction, engineering, integration — not vendor MSRP
- What stays. What has to go. And why.
