Source Atlantic: From Split Tenants to a Single, Governed Power Platform

Fragmented environments. Complex dependencies. Zero room for disruption.

‍

Source Atlantic needed to consolidate its Microsoft Power Platform and Dynamics 365 environments into a single, governed tenant without losing operational momentum. Existing assets spanned multiple tenants, integrations, and user groups, each with unique security and compliance baselines.

‍

This was not a lift and shift. It was a rebuild of the platform’s operating model, aligning apps, automations, reports, and data under one secure, scalable framework. The goal was to unify the foundation while preserving data integrity, restoring integrations, and minimizing business impact.

BITSUMMIT engineered a migration program designed for precision and control. Each phase was executed with deliberate governance, technical validation, and documentation to ensure a stable and repeatable foundation for future scalability.

‍

Initiation and Planning Discipline
• Conducted project kickoff, stakeholder alignment, and risk identification with schedule and prerequisites validated
• Assessed current Power Platform and Dynamics 365 assets, integrations, and security posture
• Produced a comprehensive migration plan mapping dependencies, managed identities, and service account strategy

‍

Tenant Build and Security Foundations
• Configured development, test, and production environments for Power Platform
• Mirrored Dynamics 365 settings, roles, and permissions
• Applied Conditional Access, compliance policies, and security baselines
• Established service accounts and managed identities to future proof automation governance

‍

Migration Execution and Integrity Controls
• Migrated Power Apps, Power Automate flows, Power BI datasets, and Dynamics 365 data and customizations with data integrity preserved
• Updated environment variables, reconnected data sources, and documented configurations for continuity

‍

Integrations, Testing, and Readiness
• Re-established gateways, custom connectors, APIs, and third party integrations
• Drove functional, performance, and security testing, followed by structured UAT with feedback and sign off
• Delivered communication kits, training materials, and adoption support plans

‍

Cutover and Post Migration Support
• Executed a low impact cutover with real time monitoring and issue resolution
• Provided post migration validation, documentation updates, and assisted with decommissioning legacy environments

The engagement produced a consolidated, governed tenant that strengthened platform reliability and set the stage for long term governance. BITSUMMIT delivered a structured migration that prioritized transparency, documentation, and future readiness.

‍

• Comprehensive migration blueprint produced with full assessment, risk plan, and timeline to steer execution
• New tenant environments configured to best practices with security and compliance applied
• Power Apps, Flows, Power BI, and Dynamics 365 workloads migrated with data integrity preserved
• Gateways, connectors, and APIs re-established and validated end to end
• Testing, UAT, and training materials delivered for readiness and adoption
• Seamless cutover achieved with monitoring, validation, and closure documentation

‍

The Path Forward

‍

With the consolidated tenant now live, Source Atlantic is positioned to operate a managed identity model for automations, maintain quarterly governance cycles, and scale modernization across Power Platform and Dynamics 365.

‍

BITSUMMIT’s structured migration approach created a repeatable foundation ready for future app modernization, analytics, and secure automation at scale.
