Software Modernization

Established web applications and legacy systems are renewed step by step, without jeopardizing ongoing operations.

Overview

What it is — and what it includes.

Software modernization is the controlled renewal or replacement of established software (legacy) — typically web applications on outdated framework versions, untested PHP codebases or legacy systems behind a portal. Batunet modernizes step by step — often using the strangler fig pattern — so that the old system keeps running until the new one has safely replaced it.

Scope of services

  • Analysis of the existing system and its risks
  • Step-by-step replacement (strangler fig)
  • Data migration with a tested backup and restore procedure
  • Parallel operation and controlled cutover
  • Knowledge retention and documentation
How a project runs

From the first conversation to a running system.

Every project follows the same four steps. You see and review interim results along the way, not only at the end.

  1. 01

    Understand the goals and requirements

    The first conversation, held with our management, covers your project, your processes and the systems already in place. We then write down goals and requirements and tell you openly whether custom development makes sense.

  2. 02

    Plan the solution and architecture

    We propose a technical solution, define the scope and the order of implementation, and document the key decisions together with their reasoning.

  3. 03

    Build and review together

    We develop in stages, with tests and code reviews. We present interim results regularly so you can review them early and adjust priorities.

  4. 04

    Launch and keep supporting

    After launch we take on maintenance, updates, monitoring and further development to the agreed extent. The project-specific source code and the documentation are handed over to you.

Outcome

What you have in hand at the end.

  • A path away from the legacy system that does not put operations at risk

  • Software that is maintainable and extensible again

  • Documented knowledge instead of dependence on individuals

Questions

Questions about Software Modernization

  • Do we have to replace everything at once?

    No. We replace the legacy system in parts and redirect it function by function. A big-bang rewrite is rarely the right answer.

  • What happens to our data?

    Data migration is planned, tested and made reversible. Backup and restore are proven before the cutover.
