THE STORY
Complex migration, zero downtime.
THE STARTING POINT
This Canadian immigration law firm was undergoing a divestiture requiring the full separation and migration of its Microsoft 365 environment into a new tenant. The challenge extended beyond timing, it was deeply technical. Core systems including email, collaboration tools, identity, and device management were tightly integrated and critical to daily operations.
With no tolerance for downtime, the organization needed a structured, low-risk approach to execute the migration without disrupting client service.
THE CHALLENGE
-
Strict Timeline
Required full tenant-to-tenant migration within a four-week window. -
Zero Downtime Tolerance
Continuous access to essential tools like Exchange, Teams, and SharePoint was critical. -
Complex Environment
Highly interconnected systems across identity, collaboration, telephony, and devices. -
Cross-Team Coordination
Required precise alignment across internal teams and external partners.
THE SOLUTION
-
Assess & Plan
We conducted a discovery workshop and mapped dependencies across identity, collaboration, and infrastructure. -
Design a Target Environment
We defined future-state tenant architecture including identity, licensing, and configurations. -
Phased Migration Plan
Our technical experts migrated services in controlled stages to maintain continuity and reduce disruption. -
Post-Migration Stabilization
Quadbridge provided hyper care support and coordinated stakeholders to ensure a smooth transition.
