Legacy logic is difficult to inspect
Application behaviour, rules and dependencies are buried across source artefacts and undocumented conventions.
Ternyx by Splexion
Application Modernisation Accelerator.
Ternyx begins once a modernisation direction is approved, then supports transformation through Lens, Nexus and Forge.

Forge
Generate target-platform assets with traceability.
The problem
Why Ternyx is needed.
Even with a clear target direction, legacy transformation is slowed by manual discovery, repeated interpretation and disconnected decisions.
Transformation decisions scatter
Mappings and exceptions are resolved across meetings and delivery tools without one controlled decision context.
Source-to-target lineage weakens
Generated or rewritten assets become difficult to trace back to source evidence and approved choices.
What Ternyx does
A controlled acceleration path from legacy artefacts to target assets.
Ternyx inspects legacy application artefacts through Lens, supports AI-assisted and human-controlled transformation decisions through Nexus, and generates target-platform assets through Forge. Every stage preserves context so teams can resolve exceptions without losing the relationship between source, decision and output.
Who it is for
Built for accountable teams.
Modernisation delivery teams
Platform migration teams
Architecture and engineering groups
Controlled process
Start. Produce. End.
1
Where it starts
Lens — Ingress
Inspects source artefacts, application structure, embedded rules and dependencies from an approved modernisation direction.
2
What it produces
Nexus — Central
Presents mappings, exceptions and transformation choices for AI assistance, engineering judgement and accountable approval.
3
Where it ends
Forge — Egress
Generates target-platform assets with traceability to the source evidence and decisions that shaped them.
Core capabilities
What the customer receives.

- Reviewable mapping decisions
- Managed exception queue
- Generated target-platform assets
- Source-to-target traceability
- Engineering handover package
Governance and human control
Intelligence remains reviewable.
Ternyx keeps automation inside a reviewable decision chain and supports customer-defined data, model, hosting and access boundaries. Engineers can inspect mappings, resolve ambiguity, approve exceptions and trace generated output back to source artefacts and approved decisions.
- Human-controlled transformation decisions
- Exception review and approval
- Source-to-target lineage
- Sovereignty-aware deployment boundaries
Ternyx and delivery services
Generated assets move into engineering, testing and controlled delivery.
Splexion specialist services, customer teams and delivery partners can take generated assets through implementation, testing, deployment, cutover and independent assurance.
