Case Study Spotlight
Executive Briefing Before Cutover
To meet the executive relocation window, we facilitated a leadership briefing that visualized coexistence risks, dependencies, and success metrics before discovery began.
Key Moves
- Mapped executive assistants and shared mailbox dependencies into the migration backlog to prevent orphaned permissions.
- Demonstrated a zero data-loss rehearsal with a pilot mailbox set, building confidence in the rollback plan.
- Aligned facilities relocation milestones with migration waves so the calendars never collided.
Evidence of Success
- Steering committee endorsed the migration charter within 48 hours.
- Executive offices migrated during a single maintenance window with zero missed meetings.
- No escalations triggered from VIP mailboxes during the first 72 hours of coexistence.
