Legacy .NET Modernisation Checklist

Expose architectural risk, challenge rewrite assumptions and identify the safest next move for a business-critical .NET platform.

What the checklist helps you assess

  • Business and operational exposure
  • Architecture, coupling and dependencies
  • Framework support, security and ownership
  • Testing, deployment and rollback maturity
  • Data, integrations and observability
  • Team knowledge and decision ownership
  • Whether a rewrite case is genuinely ready

What you will leave with

A scored risk profile, the three areas creating the greatest exposure and one decision that can materially reduce uncertainty in the next 30 days.
