This acquisition presented an opportunity for the customer to extend its footprint to include water and wastewater treatment technologies and solutions, but it also introduced an immediate and complex IT integration challenge spanning two distinct Microsoft 365 environments.
Business Objective
As part of its post-acquisition integration roadmap, the organization needed to bring the acquired company's entire workforce, data, and applications onto its own M365 environment without disrupting ongoing projects or client commitments.
The organization defined three non-negotiable outcomes for the integration:
- Achieve Workforce Continuity: Bring every acquired employee into the new IT environment on day one, fully equipped to work without interruption.
- Migrate at Scale, within a Fixed Window: Complete a high-volume, multi-site data migration to a strict, non-negotiable deadline with no tolerance for slip.
- Guarantee Data Integrity End-to-End: Protect the full fidelity of every file, permission, and version record treating EPCM project documentation as mission-critical from the first day of planning.
Challenges
Despite the clear vision, several challenges stood in the way:
- Newly acquired employees needed immediate access to data and applications with no interruption to their work
- 850+ GB of data spread across 5 distinct website collections, document libraries, and thousands of documents
- Complex user roles and permission structures requiring precise mapping between tenants
- Zero tolerance for data loss given the mission-critical nature of EPCM project documentation
