WHITE PAPER
Mitigate Control Systems Risks with a Well-Planned, Phased SCADA Modernization
When any part of your supervisory control and data acquisition (SCADA) system is outdated or obsolete, there are business and operational risks your organization may be facing – from cybersecurity threats to increased downtime to challenges with maintaining and supporting your systems. While many organizations using mature or obsolete SCADA system components know they really should modernize, getting started with modernization can be difficult.
This white paper aims to help you move beyond the modernization roadblocks you may be facing by covering the following:
-
Details on the risks of continuing to run your mature and/or obsolete SCADA system
-
The many benefits of modernization
-
How to minimize risk when implementing changes during a modernization
-
An example of a recent modernization we completed for a mining client
Information on how GTH can develop a phased modernization plan that will allow you to start experiencing the numerous benefits of a modern SCADA system sooner.

Reused existing PLC programming during migration
Proven methods developed over decades in business
Transition time to new PLCs using phased approach
A single outdated Windows XP PC ran entire SCADA system
Beyond the Numbers
These additional benefits show how a phased SCADA modernization with GTH reduces risk, protects uptime, and improves operational performance.
-
Minimized downtime through phased modernization
A phased modernization approach allows upgrades to occur in planned stages, reducing operational disruptions and avoiding extended shutdowns while maintaining production continuity throughout the transition.
-
Reduced cybersecurity risk via supported OS updates
Modern SCADA systems run on supported operating systems that receive regular security updates and patches, helping protect plant floor and enterprise networks from evolving cyber threats and vulnerabilities.
-
Ability for old and new systems to coexist during migration
Hybrid system architecture enables legacy and modern components to operate simultaneously, allowing functionality to be verified before full cutover and significantly lowering transition risk.
-
Minimized operator retraining
By reusing existing logic and familiar programming structures, modernization reduces the learning curve for operators, minimizing retraining time and helping teams adapt quickly to the upgraded system.
