Legacy SCADA Migration Planning

Plan and execute legacy SCADA migrations that minimize downtime, preserve field wiring, and modernize your control infrastructure.

Legacy SCADA Migration Planning focuses on reducing the operational risk of replacing aging control hardware. We advocate for migration strategies that utilize existing field wiring and enclosures where possible to minimize installation time and cost.

Our phased cutover process ensures that critical telemetry remains available throughout the transition, allowing for validation of new logic against legacy operations before full switchover.

Whether migrating from coordinated MOSCAD systems or legacy PLCs, GDS provides the deep institutional knowledge required to modernize your infrastructure without disrupting ongoing operations.

Key focus areas

  • Detailed I/O and wiring risk assessment
  • Phased cutover strategies to maintain uptime
  • Logic parity validation for reliable control

Implementation checklist

  • Inventory all legacy I/O and communication paths
  • Identify critical failure points in aging hardware
  • Develop rollback contingencies for every phase
