Legacy assessment and risk mapping
We establish what the system actually does — including the undocumented parts — and where the genuine risks sit: unsupported versions, single points of knowledge, brittle integrations, and data quality.
Move off rigid, expensive systems without stopping the business.
Move away from rigid, high-maintenance legacy systems: modernization roadmaps, replacement strategy, integration design, migration planning, and phased execution.
If several of these are true for your business, this service is usually where the fastest return sits.
Not every element applies to every business. We scope to what your operations need, and say so when something is not worth doing.
We establish what the system actually does — including the undocumented parts — and where the genuine risks sit: unsupported versions, single points of knowledge, brittle integrations, and data quality.
Not everything should be rewritten. We assess each component for retire, retain, re-host, re-platform, refactor, or replace — and justify the call with cost and risk, not fashion.
The bridge that lets old and new run together. This is what makes a phased migration possible instead of a terrifying big-bang cutover at midnight on a Saturday.
Extract, clean, map, load, and — critically — prove it. Every migration ships with reconciliation reports your finance team can sign off against.
Module by module, or site by site, with a rehearsed rollback at every step. The business keeps trading throughout.
The saving only lands when the old system is genuinely switched off. We plan archival, statutory retention, and licence termination as part of the programme, not as an afterthought.
Indicative ranges from comparable engagements. Your assessment produces numbers for your own operations.
Every engagement ends with artefacts your team can use, extend, and operate without us. Documentation and handover are part of the scope, not an optional extra.
Each phase is independently valuable. You can pause after any of them and still be better off than when you started.
Including the customisations nobody documented and the Excel files that quietly became part of the process.
Retire, retain, re-host, re-platform, refactor, or replace — with the cost and risk case for each.
Integration first. Once old and new can talk, migration stops being a single high-stakes event.
Lowest-risk module first to prove the process, then progressively the core. Each phase reconciled and signed off.
Archive, terminate licences, switch it off, and confirm the run cost actually fell.
Chosen for how well it is supported and how easily your team can take it on — not for how impressive it sounds.
The sectors where we most often deliver this work, and where the payback is usually fastest.
Yes, and it is often the right answer. Tally handles statutory accounting well; the pain is usually everything wrapped around it. We integrate rather than replace, so finance carries on unchanged while operations move onto a modern system.
By not doing one. The integration and coexistence layer comes first, so old and new run in parallel. Each module migrates independently, reconciles, and has a rehearsed rollback. No single weekend decides the outcome.
It usually is, but cleansing is scoped as real work rather than assumed away. We profile the data early so the true condition is known before commitments are made, and we agree explicitly what gets cleaned, what gets archived, and what gets dropped.
That is a common starting point. We reconstruct behaviour from the database, the running system, the integrations, and the people who use it daily. It takes longer than reading good documentation, but it is entirely tractable.
Start with a short conversation. We will tell you honestly whether this is the right place to begin, or whether something else pays back faster.
