Six phases. No improvisation.

Every engagement starts with a genuine audit of the live data, not the original system specification. We profile volumes, duplication rates and completeness across every domain in scope, across every source system.

The output is a data quality score per domain, ranked by risk, so the programme knows exactly what it's dealing with before design work begins.

Every source entity is mapped to its D365 target explicitly, field by field, with transformation rules documented rather than left to build-time interpretation.

The cleansing plan from discovery is finalised here, and every mapping decision is signed off by your finance and functional leads before a single line of ETL is written.

We build the migration machinery — DMF/DIXF templates, KingswaySoft packages, and SQL staging tables — against the mapping agreed in design, with unit tests on every transformation rule.

Nothing here is generic. Every package is built against your specific source structures and your specific D365 configuration.

Two full mock migrations run end to end, each followed by a formal reconciliation report comparing source and target balance for balance, record for record.

Your team runs UAT against the second mock. Nothing proceeds to cutover planning until every domain reconciles and UAT is signed off.

The final load runs against the cutover plan built during design, with every domain reconciled against source one last time before go-live is cleared.

This is the highest-pressure phase of the engagement, and it's run against a rehearsed plan, not improvised on the night.

The first weeks after go-live surface small issues no mock migration can fully predict — we're on hand to correct them fast.

The engagement closes with a written closure report, and clients can move onto a Post-Go-Live Retainer for ongoing support beyond that.
