Application / Platform Migration

Migrate applications, databases and workloads off legacy platforms with minimal downtime.

Network infrastructure supporting a platform migration

// overview

Assessment, re-platforming and cutover of applications between environments — legacy to cloud, platform to platform, data centre to data centre — with reversibility at every stage.

problem.log

The business challenge

Migrations are scoped as lift-and-shift and discovered as re-engineering. Interfaces, batch dependencies and undocumented integrations surface late, at the worst possible cost.

  • ›Undocumented integrations discovered during cutover
  • ›Performance characteristics changing after the move
  • ›Rollback theoretical rather than tested

build.plan

How we solve it

Dependency and performance discovery precede any migration wave. Waves are sized to be reversible, and each is rehearsed against production-like data before execution.

  • +Full dependency and interface discovery before wave planning
  • +Performance baseline captured and re-verified post-move
  • +Rehearsed, reversible waves with business sign-off

Scope the build

Send us the spec, the legacy system or the integration nobody wants to touch. We will come back with an architecture, a sprint plan and a date — within one business day.
