Legacy control system extension, migration and replacement services

RoviSys provides legacy control system migration expertise and resources backed by a proven and flexible conversion methodology, all built on intimate knowledge of legacy and modern controls and years of migration experience.

Whether you are looking to extend the life of your current controls, replicate existing capabilities in a supportable system or add new capabilities, we can help you understand the possibilities and then plan and implement your desired outcome.

RoviSys could be your best resource for migrating your plant to modern controls. Why? Because we know and work with legacy and modern control systems. Because, when it comes to solutions, we put client needs and objectives, rather than a platform or approach, first. And we have the resources, attitude and systems to get projects done.

Legacy DCS migration methodology

Good planning minimizes migration risks while enabling you to capture opportunities to add capabilities. From our DCS migration and process automation project experience, we’ve developed a methodology that focuses on key factors for migration success. This includes detailed cutover planning to manage or even eliminate downtime. See the steps.
