Migrating 150 billion Aveva Historian records with zero data loss to Canary Historian.
“The question is no longer whether eDNA is supported; it is not. The question is whether the organisation can afford to lose access to the operational knowledge contained within it.”
For many industrial organisations, decades of Operational Technology (OT) data represent an irreplaceable enterprise asset. Following the official end-of-life (EOL) and support milestone for the eDNA platform on May 31, 2026, a key customer faced a critical risk profile. Any significant platform issue post-EOL would jeopardise historical data access, threatening permanent loss of operational history and prolonged outages due to limited recovery options.
Parasyn was engaged as the Operational Technology Delivery Partner to successfully execute a high-volume data migration from the legacy eDNA system to a modern repository with open architecture. The objective was to completely de-risk the enterprise while significantly enhancing its long-term data management and operational intelligence capabilities with zero data loss.
Parasyn applied a structured Systems Engineering framework and developed an intelligent adaptive migration layer.
To guarantee zero operational downtime and mitigate risk during the high-volume data migration, a structured implementation methodology was executed through stakeholder alignment workshops, a rigorous pilot phase to validate throughput and schemas, and a staged, multi-phase rollout monitored in real time to protect critical infrastructure networks.
The sub-project concluded with a formal handover in July 2026, meeting the customer's key objective including cost allocations.
Parasyn identified several critical insights to ensure future utility data migration projects achieve a similar result:
