Mainframe modernization
Application, data, and workflow modernization for environments where regressions are expensive.
Critical systems modernization
Modernization is not a prompt. It is accountable change in production.
MSS combines AI-assisted engineering with the human ownership, validation, and release discipline needed for mainframe and Unisys environments.

Where MSS comes in
Services shaped around the hardest parts of modernization.
Every program starts with scope, constraints, and validation criteria. From there, MSS can lead the change directly or work inside a wider SI delivery model.
Unisys migration
Specialist experience for platforms many generic modernization teams cannot credibly cover.
XGEN conversion
Focused conversion capability for programs with non-standard rules, dependencies, and data paths.
How it works
Automation where it is reliable. Expert judgment where it matters.
Map dependencies, data flows, jobs, interfaces, and operational constraints before change starts.
Use AI for acceleration across discovery, conversion, documentation, and test generation.
Keep architecture, equivalence, release decisions, and client accountability with experienced people.
Visible delivery
Modernization tracked as work, not scattered documents.
Clients and delivery partners need more than status slides. MSS programs are organized around shared evidence: scope, assumptions, converted assets, test status, risks, and release decisions.
