Customisation modernisation
From legacy Java customisations to modern Automation Scripts.
Many enterprise Maximo estates still carry old Java customisations from the 7.x era — hard to maintain, hard to upgrade, and a blocker on the road to MAS. We modernise that codebase: review every Java customisation, decide what stays, what becomes configuration, and what is rewritten as an Automation Script. Result: an upgrade-ready Maximo with dramatically lower long-term cost of ownership.
Legacy Java customisations are the silent tax on a Maximo estate. They were the right answer ten years ago. They are the wrong answer now: opaque to the business, expensive to test, painful at every upgrade, and a blocker on the road to MAS. Modernising them removes that tax permanently.
What we deliver
- Inventory and assessment of every Java customisation in the estate
- Per-item decision: keep, retire, move to configuration, or rewrite as Automation Script
- Modernisation delivered in waves, with behaviour preserved and tested before cutover
- Clear migration of integrations and security context where required
- Documentation that survives the rewrite, so the next team can support the estate
- A measurably lower long-term cost of ownership and a much easier next upgrade
How it fits with the rest of the programme
Modernisation pairs naturally with Maximo to MAS upgrade and with Maximo 7.6 Extended Support: take the right code into the next version, not all of it. It is the partner discipline to Maximo configuration — together they decide what should be code at all. On large estates it sits inside an Upgrade Factory programme.

Customisation modernisation — frequently asked questions
- Why move from Java customisations to Automation Scripts?
- Java customisations from the 7.x era are difficult to maintain, expensive to test, and a major drag on every upgrade. Automation Scripts are the supported, modern way to extend Maximo, are visible inside the application, and survive upgrades far better. Modernising the codebase removes a structural cost from the estate.
- Do you rewrite everything as Automation Scripts?
- No, that would be wasteful. We review every Java customisation and decide three things per item: keep as-is, retire because the requirement no longer holds or can be met by configuration, or rewrite as an Automation Script. The mix is decided on evidence, not a blanket rule.
- How long does a modernisation programme take?
- It depends on the volume of custom code and how it is structured. We start with a fixed-scope assessment, give you a credible inventory and effort estimate, and then deliver in waves so the estate keeps moving forward.
- Can this run alongside an MAS upgrade?
- Yes, and it usually should. The upgrade decisions and the modernisation decisions are tightly linked: you want to take the right code into MAS, not all of it. We routinely combine modernisation with Maximo to MAS upgrade and with Maximo 7.6 Extended Support.
- Will we lose any business behaviour?
- No. Behaviour is preserved by design; only the implementation changes. We test the modernised version against the old one before anything goes live.
