M&A tenant consolidation for a public accounting firm

Public accounting firm

Challenge

A multi-year acquisition program meant every deal arrived with its own Microsoft 365 tenant, its own devices, and its own security posture.

Approach

An advisory engagement across the program, migrating each acquired company into the target tenant: Teams, OneDrive, SharePoint, Defender, Intune, and the endpoint devices themselves.

Outcome

Three companies and 350 users consolidated into the target tenant, with a repeatable pattern ready for the next acquisition.

The same firm later moved its telephony to Microsoft Teams Phone: system design, licensing, number porting, and configuration of auto attendants and call queues.

Technology: Microsoft Teams, OneDrive, SharePoint, Microsoft Defender, Intune, endpoint devices, Teams Phone with Calling Plans.
