Legacy application support and software maintenance

Legacy application support for software the business still depends on.

When the original developer has left, the supplier is moving on or an ageing application still runs part of the business, Galvia can help take ownership, stabilise the software and create a workable support and modernisation path.

Tell us what the application does, why the support arrangement is changing and what currently feels risky. You do not need a finished specification.

When to bring us in

When the software still matters, but the support around it does not.

A handover problem can quickly become an operational problem. The first job is to make ownership, access and the release path understandable before more change is added.

01 / SUPPLIER LEAVING

The software still matters, but the original team is moving on.

You need more than a repository transfer. Accounts, environments, deployment, data, support history and unresolved work all matter.

02 / CHANGES FEEL RISKY

Small fixes take too long or break something else.

Limited tests, manual deployment and tightly coupled code can turn routine maintenance into an operational risk.

03 / NO CLEAR FUTURE

You need to keep the application running while deciding what comes next.

Support and modernisation are not the same decision. The immediate goal may be continuity while a phased improvement plan is developed.

How we start

Secure the software first. Then decide what should change.

We start with access, ownership and the current operating reality. Once the immediate support path is understood, we can agree the first piece of paid work and whether the longer-term answer is maintenance, targeted refactoring or wider modernisation.

  1. 01

    Take control of access and knowledge

    Confirm the code, hosting, environments, accounts, deployment process, data and existing documentation.

  2. 02

    Stabilise the support path

    Prioritise production risks, repeatable release steps, critical defects and documentation that reduces dependency on individuals.

  3. 03

    Maintain, improve or modernise

    Agree the ongoing engineering capacity and whether the next step is continued support, targeted refactoring or a wider modernisation programme.

What happens after the enquiry? The initial conversation is not a full technical audit. Repository access, detailed investigation and implementation are scoped separately.

Published project examples

Published examples of taking software forward without losing control.

These public Galvia projects show modernisation, developer handover and integration around existing products. They are related engineering evidence, not a claim that every inherited application needs the same route.

ASM / legacy modernisation

Desktop software moved to a browser-based, cloud-ready application.

Galvia helped modernise an established freight-customs product and enabled the client team to continue development.

Stimare / product integration

Developer-facing software built around existing hardware.

Galvia created a shared mobile SDK, demo application and supporting documentation for barcode-scanner integration across Android and iOS.

The people behind the work

Talk to the people
behind the work.

Galvia is a Belfast software development team. We work alongside your people, explain the trade-offs and document what we build so the result can be understood and maintained.

You can get to know the team and how we approach a project before sharing your brief.

How Martin approaches a project

What the work can involve

Software support services for applications you cannot simply switch off.

Ongoing support is part technical, part operational. The useful work is often a combination of recovering context, making releases safer and reducing dependency on one person or supplier.

Application support and maintenance

Provide engineering capacity for defects, small changes and operational support around an existing application. We first establish what can be supported safely and what needs stabilisation before routine maintenance makes sense.

Inherited codebase takeover

Take over software built by another developer or supplier where source code, environments and knowledge need to be brought under clearer ownership. The emphasis is a controlled transition rather than pretending a repository alone is a handover.

Release, deployment and documentation improvement

Reduce the risk around routine changes by improving repeatability, documentation, testing and deployment where the current setup allows it. The exact work depends on the codebase and infrastructure we inherit.

Planned transition into modernisation

Keep the application running while identifying the parts that create the most cost or risk. Where larger change is justified, our legacy software modernisation work can turn that into a phased programme.

Keep the technical route proportional to the problem. Support does not automatically mean rebuilding the application. The first objective is to understand what must remain dependable now and what can be improved in a controlled sequence.

Before you enquire

The practical
questions.

Can you support software written by another company?

Yes, where the business has the necessary rights and access and the application can be understood and operated safely. We normally begin by establishing the source, environments, deployment path, documentation and immediate risks before agreeing ongoing support.

What do you need from the outgoing supplier or developer?

Useful handover material includes source repositories, hosting and environment details, deployment instructions, integration information, documentation, support history and outstanding issues. Do not send passwords, API keys or customer data through the enquiry form.

Can you provide ongoing maintenance without rebuilding the application?

Often, yes. If the existing application can be supported safely, maintenance and incremental improvement may be the right answer. A rebuild is a separate decision and should be justified by the constraints of the current system and the business need.

What if we do not own all of the hosting or source-code accounts?

The first step is to establish what access and ownership the business currently has and what must be transferred. That may require cooperation from the existing supplier. We can help identify the technical gaps, but legal ownership questions should be resolved with the appropriate advisers.

How do support and legacy modernisation fit together?

Support is about continuity and safe ongoing change. Modernisation addresses deeper structural constraints. A business can stabilise support first and then move into targeted refactoring, migration or replacement when there is a clear reason to do so.

Can you work as part of our existing technical team?

Yes. Galvia can provide engineering capacity alongside an internal team, with the level of involvement agreed around the backlog, ownership and technical context.

Tell us what the application still needs to do

What needs to stay
working while ownership changes?

Tell us which application is involved, why the support arrangement is changing and what feels most urgent. We review each enquiry before arranging a call.

  • A person reviews the project before a call is arranged.
  • No passwords, API keys, customer records or other secrets in the form.
  • No work or fees are agreed by submitting this form.

Commercial conversations are led by Martin Naughton, Galvia’s founder and solution architect. Meet Martin.
