Retain & extend
- When to consider it
- The core system still works and supports the next requirement.
- What to check
- Check maintainability, supported dependencies and whether a targeted feature or integration is practical.
Legacy modernisation & migration
We assess older software and plan practical changes to its code, platform, integrations or data. The starting point is understanding the business workflows the system supports and the limitations that need to be addressed.
Compare the options
Choose the extent of change after reviewing the business workflows, dependencies and operating constraints.
Development scope
Review functions, business rules, code, dependencies, infrastructure and integration points.
Compare extending, refactoring, replacing components or rebuilding a defined part of the system.
Develop the selected changes around agreed workflows and integration requirements.
Define mappings, migration steps and checks for the records involved.
Plan testing, cutover, recovery arrangements and documentation appropriate to the agreed changes.
Deliverables & handover
An assessment can establish the options and migration plan before implementation is agreed. Deliverables depend on the selected route and the parts of the system being changed.
Findings, dependencies, practical options and the agreed stages.
Replacement components, updated services or migration tools and validation records where included.
Testing and cutover arrangements, recovery planning and handover documentation for the agreed work.
How we work
Identify workflows, data, dependencies and the people or systems affected.
Define what to retain, what to change and how to divide the work into stages.
Develop the selected changes and check functionality, integrations and any data movement.
Agree cutover, recovery and handover arrangements, then plan subsequent support.
Assessment focus
Identify essential workflows, acceptable interruption and the needs of affected users.
Understand sources, formats, quality, destination requirements and how migrated records will be checked.
Review integrations, infrastructure and the access needed to change the system.
Agree readiness checks, transition responsibilities and the appropriate recovery arrangements.
Before you decide
An older product does not automatically need replacing. Start by separating the business problem from assumptions about the technology.
A list of screens is a starting point. A useful estimate also needs the behaviour, data, dependencies and delivery work behind those screens.
Practical questions
No. An assessment may support updating components, introducing new services or changing the system in stages. The decision follows the business requirements and the condition of the system.
Data migration can be included after reviewing the sources, formats, quality and destination requirements. The scope includes the agreed mappings, validation and transition arrangements.
That depends on the architecture and the changes involved. We assess continuity requirements and agree how any interruption, parallel operation or staged cutover should be handled.
