Legacy migration

Move from legacy software without losing your data

We migrate history, relationships and essential customisations from systems that are unsupported, restricted or no longer fit for purpose.

01

What the service addresses

Unsupported software stops receiving dependable security fixes and becomes harder to integrate whenever regulations, interfaces or operating environments change. The difficult part is rarely buying the replacement product. It is extracting usable data without losing transaction history, reference relationships or the operational logic your team relies on. We begin with an inventory, dependency map and measurable completeness criteria before recommending a target architecture.

  • Software inventory and support calendar
  • Vendor-neutral target selection
  • Migration of data, relationships and customisations
  • Parallel operation and reconciliation
  • Team enablement and handover
02

A verifiable migration

DATAMEN does not resell the target-system licences or work to a vendor quota. The deliverable is not a vague promise to move data: it is a controlled migration with agreed validation rules, reconciliation results and an acceptance record. Your team receives the documented data model, transformation rules and integration map needed to maintain the new environment without replacing one supplier dependency with another.

03

Migration as an AI foundation

A migration already requires the work that many AI programmes postpone: identifying sources, cleaning reference data, resolving duplicates, defining access and creating a shared model. The same foundation supports enterprise search, analytics and AI agents. A controlled migration can therefore produce two outcomes: a supported operational system and governed data that is ready for the next automation or AI use case.

Fit before scope

Is this the right starting point?

Use these criteria for an initial orientation. The final recommendation follows a review of your context, data and constraints.

A good fit when

  • Software is restricted, unsupported or creates operational risk
  • Data, history and integrations must be preserved
  • Process and acceptance owners are available

Resolve this first when

  • Only licence procurement is required without dependency analysis
  • A target was selected without validating processes and data
  • No one owns reconciliation and the cutover decision

Frequently asked questions

Frequently asked questions

Must every record be migrated?

No. Discovery determines what belongs in the live system, what should remain in an accessible archive and what can be retired.

Can migration happen without stopping operations?

The normal approach uses a parallel period. The old and new systems run together until agreed balances and critical workflows have been reconciled.

Do you sell the replacement system?

No. You select the target platform. We provide a vendor-neutral comparison and take responsibility for the data migration.
