Stambia to Semarchy xDI migration
Do you need to secure a legacy Stambia platform, prepare its move to Semarchy xDI or take over flows nobody fully understands? I turn that risky programme into a controlled migration: inventory, prioritisation, conversion, parallel run, testing and team handover.
A safe migration starts with understanding what already runs
A Stambia platform is never just the mappings visible in the studio. It contains implicit dependencies, scripts, schedules, files delivered at fixed times, manual recovery steps known by one person and business rules documented nowhere. Converting objects without rebuilding that knowledge simply moves the risk rather than removing it.
The audit produces an actionable view: active and obsolete flows, sources and targets, data volumes, processing windows, business criticality, reject handling, external dependencies and validation owners. This foundation makes honest estimation possible and avoids the familiar project whose scope doubles after three months.
What the audit checks
- Inventory of flows, versions, components and dependencies
- Business criticality, SLAs, volumes and batch windows
- Quality of logs, rejects, alerts and recovery procedures
- Compatibility of templates and components with the xDI target
- Available skills and actual documentation level
- Cutover risks, rollback scenarios and success criteria
A measurable, reversible migration delivered in waves
Map
Identify flows, dependencies, business owners and weak points. Separate what should be migrated, replaced or retired.
Pilot
Choose a representative but non-critical batch. Validate xDI conventions, templates, logs, scheduling and the delivery pipeline.
Migrate
Convert coherent batches, automate checks, compare results and document every discrepancy before the next wave.
Cut over
Run both systems in parallel where risk requires it, secure business approval, prepare rollback and hand operations over.
The target is not just xDI: it is a platform your team controls
Readable flows
Shared conventions, explicit names, reusable components without needless machinery and documentation connected to the decisions actually made.
Reliable operations
Useful logs, actionable rejects, meaningful alerts and recovery procedures tested before the first production incident.
Independent team
Regular reviews, demonstrations and progressive handover so the platform does not become a supplier’s new black box.
Engagement formats
The engagement can start with a focused audit, continue as migration support or become embedded reinforcement for your team. I can own a complete batch, frame the work of an existing team or focus only on the most critical flows.
The signals that justify an initial assessment are concrete: recurring incidents, the departure of the person who knew the platform, an ageing version, incomplete documentation, processing times that keep drifting or an announced modernisation programme. A short audit separates immediate operating risks from the actual migration programme and gives management a clear route, budget and decision points. It can also identify quick reliability improvements that protect production while the longer transformation is being prepared.

Common questions about moving from Stambia to xDI
Should every flow be migrated at once?
No. I recommend coherent waves, each with its own acceptance criteria and cutover decision. Critical flows can stay in parallel run for as long as needed.
Can you take over a poorly documented platform?
Yes. The audit rebuilds documentation from projects, schedulers, logs, databases and business interviews. Unknown areas are explicitly recorded as risks to resolve.
What deliverables will we receive?
A map, criticality matrix, estimated backlog, design rules, test and cutover plans, followed by operating documentation for migrated batches.
Do you work throughout France?
Yes, the engagement can be delivered fully remotely. Based in Valenciennes, I can also work on site in Lille and across the Hauts-de-France for workshops or cutovers that require it.
