Data Migration

Move flows and reference data onto a modern target, with a cut-over plan you can defend to a steering committee.

Why clients call us

Migration is where integration projects are won or lost, because it is the only phase with a date, an audience and no undo button. Our position is that migration is a repeatable discipline with its own methodology, not a project phase to be improvised at the end.

We draw on a dedicated migration centre of excellence inside the Alan Allman Associates ecosystem, with more than 150 critical migrations delivered in finance, logistics, utilities and government. The method is deliberately conservative: automate the transformation, and verify every record rather than a sample.

What we do

  • Assessment and cut-over strategySource analysis, gap mapping, and an explicit arbitration between big-bang and progressive migration, with the reversibility cost of each stated up front.
  • Platform modernisationWTX to ITX, MQSeries to MQ, Sterling to ACE, on-premise to hybrid. Paths we have walked before, supported by our own migration tooling.
  • Industrialised transform and loadMetadata-driven code generation, parallelised processing and scripted loads. Human error removed by design rather than by vigilance.
  • Double-development quality controlTwo developers implement independently and results are compared automatically across the full record set. Every field verified, not sampled.
  • Go-live and validationMonitored cut-over, predefined rollback, detailed logs, business sign-off on real data, and a complete audit report.
A migration is the cheapest moment to fix reference data. Cleaning identifiers, addresses and party records during cut-over pays for itself the first time a reporting or AI use case needs them.
