Take the next step without losing what already works.

An older application may still be doing an important job. Before replacing it, we examine the code, dependencies and business workflow so you can choose what to maintain, improve or rebuild.

Legacy application maintenance: an illustrated view of connected systems and engineering workflows

Understand the system before changing it.

From the existing application to a plan you can test and roll back.

Inspect the system

Review code, data, accounts and the people who know the workflow. Separate confirmed findings from unknowns.

A general process illustration. Actual scope depends on the system assessment.

Is this the right service for your team?

For organizations with an application that still matters but has limited documentation, an outgoing supplier, aging dependencies or changes that are becoming difficult to release safely.

Scope and deliverables to agree together

System assessment

Review code, versions, accounts, integrations and known issues. Distinguish confirmed findings from areas that need more investigation.

Takeover preparation

Agree access, responsibilities, backup and restore checks, and a safe place to test changes before touching production.

Maintenance and upgrades

Prioritize defects and dependency upgrades. Break modernization into changes that can be reviewed and accepted.

Documentation and continuity

Prepare runbooks and handover information. Agree recurring maintenance separately from additional development.

The proposal defines the scope and acceptance criteria for your project before work begins.

From the first conversation to delivery

  1. Inspect what exists

    Start with the application, data, infrastructure and people who know the work.

  2. Prepare a safe change

    Review backups, recovery and a test environment.

  3. Improve in stages

    Agree priorities, acceptance checks and rollback conditions.

  4. Keep knowledge available

    Document decisions and responsibilities for ongoing support.

What affects cost and timing?

Code quality, supported versions, test coverage, access, documentation and third-party dependencies determine the work. An initial assessment helps avoid estimating unknown repairs as if they were routine maintenance.

What should you prepare?

Bring the stack and versions if known, a list of recurring problems, ownership of repositories and hosting accounts, and the most important business workflows. You do not need every document ready to begin.

Which direction makes sense for the existing system?

Assess the system and business need

The foundation still fits

Maintain

Fix risks, add documentation and tests, and make the existing system easier to support.

Some parts hold you back

Modernize in stages

Separate the changes, define connections to the existing system and verify each stage.

The business need has changed

Rebuild

Compare long-term costs and plan data migration and launch before committing to a replacement.

Choose based on system condition, risk and cost, not simply the age of the code.

Questions before you start

Must we rebuild the entire application?

No. Maintaining the current application or changing selected components may be a better fit. We compare options against the business need and the condition of the system.

Can you take over from another supplier?

We first check ownership, access, documentation and contractual restrictions. A structured handover makes responsibilities and unknowns visible.

What if documentation is missing?

We can start with an assessment of the available code and environment. Investigation and documentation need to be included in the scope.
