Services / Legacy software modernisation

Legacy software modernisation with a controlled transition.

Modernise the parts of your software that limit the business. We assess dependencies, preserve useful systems and plan data transfer, integration and rollout around daily operations.

Scope & fit

Change the system without losing what works.

Modernisation starts with the software you already use: where it slows work down, what remains useful and which dependencies limit change. We may recommend extending it, connecting new modules or replacing it in stages.

Assess the current system

We map dependencies, user roles, data and operating constraints to identify which parts of the system need to change.

Choose what to change

We compare extending the current platform, connecting new modules and replacing components against the required business workflows.

Migrate & synchronise

We transfer agreed records and history, reconcile the results and implement the exchanges needed while old and new systems operate together.

Plan the transition

We prepare acceptance checks, users, cutover steps and recovery procedures before the new workflow enters daily use.

Is this service right for you?

Best fit:
Owners of a working platform whose limits or maintenance risks block change.
First useful result:
An assessment defining the first workflow to migrate or replace and its recovery requirements.
What can stay:
Keep the live system serving users while we test the first replacement workflow.
Scope to agree:
Implementation, the cutover plan and support takeover are agreed after the assessment.
To get started:
Bring an architecture overview, known incidents, data owners, available access and release constraints.
Data migration and integration

Keep old and new records consistent during transition.

We assign an authoritative source to each record, define the direction and timing of updates, and handle duplicates and conflicting changes. Trial exchanges and reconciliation establish whether the source systems can support the required synchronisation.

Operational reporting

Preserve the reports people rely on.

We record the reports, calculation rules and historical comparisons your teams rely on. Together, we choose which reporting tools to keep, which views to rebuild and which data to synchronise. Before switching, we reconcile agreed figures against the same source records and reporting period.

Alongside your engineers

Keep your technical team involved in the decisions.

Your CTO and engineers bring the history of the system, its constraints and operating standards. We agree how that knowledge shapes architecture, code review, delivery and production ownership.

Decisions and review

Name who approves architecture, reviews changes and accepts a release. Work in the agreed repository and make dependencies on your team visible in the plan.

Shared operations

Divide deployment, monitoring, backup and incident duties. Your team can retain agreed responsibilities while our scope covers the engineering and support you need.

Example assessment / Distributor

Know what to keep, extend and replace.

A distributor uses spreadsheets, a warehouse application and separate accounting. This fictional example shows how an assessment turns that setup into a staged plan.

Keep

Accounting

Retain posted entries and financial ownership in the current system.

Required check

Finance validates the exchange fields and a reconciled sample.

Extend

Warehouse application

Expose the stock and shipment information the new order view needs.

Required check

The technical owner proves supported access, freshness and failure handling.

Replace in stages

Order spreadsheets

Introduce one order record with identifiers, permissions and an exception owner.

Required check

Operations accepts a pilot and reconciles open orders before switching ownership.

Assessment output
  • Dependency map
  • Decision record
  • First-release scope
  • Open risks and owners

Prove the warehouse connection first.

Warehouse access is unverified in this example. Test the interface before promising automatic stock updates. A scheduled export needs a visible update time and warehouse confirmation before delivery is promised; if that delay is unacceptable, revisit the scope.

One team. One pilot workflow.

Start with customer-linked orders and an exception queue. Keep accounting and stock ownership in their current systems; defer forecasting and additional sites.

Included in the pilot

Source mapping, permissions, reconciliation, user preparation and recovery checks.

Agree who can approve or stop the launch.

The delivery lead prepares the rehearsal; operations accepts the workflow; finance checks totals.

Before switching systems

Agree the recovery owner, how new transactions will be reconciled and when the old workflow stops accepting changes. These checks determine whether the proposed cutover can proceed.

Example / Customer record transition

What happens to a record in a staged migration?

An existing CRM holds customer 9001. The new system needs that customer, its contacts and its order history. The transfer rules are agreed from your data and systems.

01

Identify

Match the source record to its destination using agreed identifiers. Flag missing fields or potential duplicates for review.

02

Transfer & check

Import the agreed customer and related history, then compare selected records and totals with the source.

03

Repeat safely

If an update arrives while systems coexist, apply the ownership and conflict rules instead of creating a second customer.

Definition:
Count open orders whose planned dispatch date precedes the report date. Exclude cancelled and completed orders.
Source:
Order and fulfilment records from the agreed systems.
Reconciliation:
Compare counts and order IDs with the source at the same timestamp. Investigate missing or duplicate rows.
Next action:

Planning guides

Plan scope, integrations and launch.

Budget

Separate assessment, transition and ongoing operation.

The budget depends on what can stay, what must change and how long old and new systems need to coexist. Scope dependency investigation, trial transfers, integration changes, reconciliation and recovery preparation. A replacement estimate needs evidence from the current system.

Starting budget

From USD 50,000

For a full custom software project. We estimate your agreed scope before work begins.

Payment model

Hourly or fixed price

An hourly team for evolving work, or a fixed price for a clearly defined module.

After launch

Plan operating costs

Paid support, hosting and third-party services are scoped separately from development.

Start with the context you already have.

Bring an architecture outline, known incidents, release constraints and an overview of available code, hosting and data access. If further investigation is needed, we can agree a separate paid assessment before estimating implementation.

Questions

Questions about this service

Can we keep operating during the transition?

We plan around operating hours and critical workflows, using staged rollout or parallel operation where the systems allow it. Rehearsals, data checks and a fallback procedure come before cutover. Any necessary service interruption is agreed in advance.

Is synchronisation the same as migration?

Migration transfers an agreed set of records and history. Synchronisation keeps selected data aligned while systems continue to operate. A phased transition may need both, with clear ownership of updates and checks for duplicates, conflicts and totals.

What if the old system has no suitable API?

We inspect supported exports, database access and vendor options, then test a candidate method on sample data. A scheduled exchange, an intermediate service or staged replacement may be more suitable than direct integration. The choice depends on access, update timing and the effect on daily work.

Can you modernise only one part?

Yes. We identify a component with a clear boundary, map its dependencies and design the connections to the retained system. Implementation includes tests of the workflows that cross that boundary, plus data transfer, user preparation and recovery steps for rollout.

What can an initial modernisation assessment produce?

The agreed deliverables can include a dependency map, decisions on what to retain or replace, a migration approach, open risks and an implementation estimate. They support a decision on the first release and any investigation still needed before development.

How do you handle security while two systems coexist?

We define record ownership, restrict access to migration tools and temporary copies, and test permissions in both environments. The transition plan assigns backup, recovery and incident responsibilities, including when temporary access and copies are removed.

Will you help our team learn the new system?

Yes. We plan onboarding around the work each role needs to do, then prepare the agreed walkthroughs, instructions and administrator guidance. We help staff practise representative tasks before rollout and use their feedback to address confusing steps. Training and launch assistance are included explicitly in the delivery plan, so your team knows what help to expect.

Will you stay involved after launch?

Yes. We help arrange a support plan before release, with agreed coverage, a way to report issues and clear operating responsibilities. We can handle the agreed maintenance and help investigate problems, while reviewing user feedback with you for future improvements. Ongoing support and new features are priced separately, with the terms explained before the system enters daily use.
