SAP Migration in Portsmouth
Migrating Portsmouth organisations to S/4HANA, where custom code remediation is almost always the longest task. The underlying data model changed, so developments written against the old structures have to be found, assessed and adapted — and in an estate built over two decades, nobody currently employed knows what half of them do.
Why this comes up
The problem
There are several thousand custom objects, no documentation, and no way to tell which are still in use.
What you get
What we deliver
- Custom code inventoried and usage measured, so dead objects are simply dropped
- Remaining developments assessed against the changed data model
- Migration approach chosen deliberately rather than by default
- Master data cleansed before the move, since the new model is stricter
- Cutover rehearsed at full volume, with the timings measured not estimated
- Fallback defined and tested, because a failed cutover needs a way back

SAP Migration in Portsmouth — common questions
- Why is custom code the long pole?
- Because there is more of it than anyone expects and the data model beneath it changed. Each object has to be located, assessed for whether it still functions and still matters, then adapted or retired — and that is thousands of small decisions rather than one large task.
- How do we decide what to keep?
- Measure usage before debating it. Execution statistics reliably show that a large share of custom developments have not run in years, which converts an argument about business value into a short list of things that genuinely need attention.
- Why cleanse master data first?
- Because the new model enforces things the old one tolerated. Records that were merely untidy become blocking errors during conversion, and finding that during a cutover rehearsal is inconvenient — finding it during the real cutover is considerably worse.
- How many rehearsals are enough?
- Enough that the timings are known rather than projected, which is usually more than planned. The cutover window is fixed by the business, and each rehearsal both shortens the runtime and surfaces the steps that were missing from the plan.
- Do you work with businesses across Hampshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Portsmouth and the surrounding Hampshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Portsmouth businesses do you usually work with?
- Port, ferry and defence logistics systems, plus visitor operations for the waterfront attractions. Beyond that we work across Marine & Defence, Ports & Ferries, Higher Education, Retail and Tourism.
- Do you cover the areas around Portsmouth?
- Yes — we work throughout South East, including Southampton, Chichester, Brighton. Portsmouth is an urban area of roughly 240,000+, and we take on work across the wider Hampshire region rather than the city boundary alone.
