Anonymized case study. Client name and identifying metrics are withheld. Patterns reflect representative senior .NET programs.
Executive summary
A U.S. services organization ran Dynamics 365 Sales, SharePoint Online, and a custom .NET billing API with ad hoc integrations. IT needed governed releases compliance could sign.
The challenge
Customer records diverged after acquisitions. Shared service accounts exceeded least-privilege expectations. Business stakeholders did not trust big-bang cutovers.
Technical approach
Integration workshops, .NET 8 middleware with managed identities, Dataverse packaging discipline, reconciliation dashboards, and dry-run cutovers with production-like test data.
Outcomes
Phased go-live with documented rollback triggers. Auditors received data-flow diagrams. IT reduced emergency production mapping changes.
