Legacy SCADA Migration Planning

Plan and execute legacy SCADA migrations that minimize downtime, reuse existing field wiring where possible, and modernize your control infrastructure.

Planning a SCADA migration helps reduce the operational risk of replacing aging control hardware. We plan to reuse field wiring and enclosures where possible to reduce installation time and cost.

We plan phased cutovers around operational needs, with agreed outage windows, temporary monitoring where needed, and a rollback procedure. Testing compares the new logic with the approved control narrative before full switchover.

For MOSCAD systems and older PLCs, GDS plans the migration around existing equipment and operating requirements to keep service interruptions short.

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
