Connecting legacy systems to modern frontends with less operational risk

Begin with the workflow: which team creates the data, which system owns it, and which team needs it next? This prevents a new interface from adding another disconnected copy. Use existing APIs when available. For older applications, assess exports, scheduled transfers, or controlled browser automation. Define field mapping, duplicate handling, and review checkpoints before rollout. Plan monitoring and recovery alongside the integration. Teams should be able to see failed transfers, retry safely, and understand which records need attention.
