Old system renewal

Older software often still does important work. Renewing it keeps it fast, easy to change and safe to run for the years ahead.

We find the parts that need attention most and renew them one at a time. Your team keeps working while the system gets faster, safer and easier to change.

What you get

  • A clear picture of what is worth keeping and what should be replaced
  • Speed, stability and security improvements first, where they matter most
  • Step-by-step rewrite of modules, while the system keeps running
  • Your data moved safely and checked after each step
  • Software your team, and future developers, can maintain

A good fit when

  • You want to change your system with confidence
  • Your system was built by a previous developer or on technology that has reached end of support
  • You want a faster, more secure system that is ready for new features

How it works

  1. Step 1

    Review

    We look at the code, data and how the system is used.

  2. Step 2

    Plan

    You get options: fix, partly rewrite or replace, with cost and risk for each.

  3. Step 3

    Renew in steps

    We replace one part at a time, with the old version as a fallback.

  4. Step 4

    Hand over

    Documentation and tests so the system stays maintainable.

For technical teams
  • Code and dependency analysis, including outdated and end-of-life components
  • Incremental replacement behind stable interfaces, so old and new run side by side
  • Data migration with checks and rollback plans
  • Test coverage added before major changes

Questions

Do we have to rewrite everything?

Usually a few modules cause most of the issues. We start with those, and much of the rest can often stay as it is.

Can we keep working during the renewal?

Yes. We change one part at a time and keep the old version ready until the new one is proven.

Can you work with code someone else wrote?

Yes. Most renewal projects start with code written by another team.
