Extend the Value of Legacy
Engineering Data
Extend the Value of Legacy Engineering Data
Nexa Digital Engineering helps clients convert and modernize existing model assets so they can continue to support engineering execution, facility modifications, upgrades, and long-term digital continuity.
Our Engineering Systems Administration services are designed to help clients:
- Preserve value from legacy engineering models
- Reduce the need for full model recreation
- Support migration to modern engineering platforms
- Improve accessibility and usability of model data
- Support brownfield upgrades and facility modifications
- Strengthen long-term digital continuity across engineering environments

Structured Support for Model Migration and Modernization
Legacy Model Assessment
We review existing legacy models, available data, and project objectives to understand conversion scope, platform considerations, and expected outcomes.
Model Conversion Planning
We help define an effective conversion approach based on the source model, target platform, project requirements, and client priorities.
PDS to Smart3D Conversion
We support the migration of legacy PDS models into Smart3D environments, helping clients transition to more modern engineering systems while preserving usable model value.
PDMS to AVEVA E3D Conversion
We support the conversion of PDMS models into AVEVA E3D to help clients modernize platform environments and improve future usability.
Legacy Data Modernization Support
In addition to model conversion, we help clients structure conversion efforts in a way that supports broader modernization goals, better maintainability, and stronger digital continuity.
Conversion Workflow Support
We provide technical and engineering support throughout the conversion process, helping clients manage requirements, standards alignment, and platform-related considerations.

A Practical Path to
Modernization
A Practical Path to Modernization
Legacy model conversion is about more than moving data from one system to another. It is about enabling continued use of engineering information in a more current and maintainable environment. Well-executed conversion can help organizations:
Avoid the cost and delay of full model rebuilds
Improve access to engineering models in current systems
Support plant modifications, expansions, and brownfield projects
Align legacy assets with modern platform strategies
Reduce dependency on outdated systems
Improve continuity across engineering teams and future projects
Preserve historical engineering knowledge in usable formats
Supporting Cost, Continuity,
and Future Readiness
Supporting Cost, Continuity, and Future Readiness
helps clients use conversion strategically to support:
Lower redevelopment effort
Better reuse of existing engineering assets
Improved continuity across platform changes
More efficient support for brownfield engineering
Stronger alignment with current engineering systems
Improved readiness for future digital initiatives
Practical Conversion Grounded in
Engineering Understanding
Practical Conversion Grounded in Engineering Understanding
Nexa Digital Engineering approaches legacy model conversion with a focus on engineering usability, platform alignment, and long-term value. We understand that conversion is not just a technical exercise. The converted model must support how engineering teams work, how facilities evolve, and how projects are delivered.
More Than Model Migration
Engineering Systems Administration often works best when supported by related technical and engineering services. This
