OPC UA Migration: What You’ll Find Here

Moving from OPC Classic (OPC DA, OPC HDA, OPC AE) to OPC UA is one of the most important infrastructure decisions facing industrial organisations in 2026. The pressure is real: DCOM vulnerabilities like CVE-2021-26414, mandatory compliance frameworks including NIS2 (EU) and NERC CIP (North America), and the growing gap between OPC Classic’s capabilities and the cloud, IIoT, and Industry 4.0 architectures that modern operations require.

This resource hub covers every stage of the OPC UA migration journey; from the strategic and financial case for migration through to hands-on configuration tutorials for engineers on the shop floor.

What you’ll find in this collection:

• Strategy: How to choose the right migration approach for your environment: wrapper-based, phased, or greenfield
• Cost & ROI: The real total cost of migration vs the hidden cost of staying on OPC Classic
• Technical bridging: How the OPC UA Wrapper and OPC UA Proxy create a bidirectional bridge without replacing existing infrastructure
• Benefits: The eight operational gains that OPC UA migration unlocks beyond security and cost
• Step-by-step tutorials: Video walkthroughs and written guides for configuring the OPC UA Wrapper and Proxy

All content is written for industrial engineers, IT/OT architects, operations managers, and compliance teams navigating the OPC Classic to OPC UA transition. New articles are published regularly as Integration Objects’ technical teams document real-world migration patterns and challenges.
