Our client is one of the world's leading pharmaceutical research and manufacturing organisations, operating across the United States, Europe, and Asia-Pacific. With over 60,000 global mailboxes, 54,000 collaboration users, and a tightly regulated compliance environment, their legacy messaging and telephony infrastructure had reached end-of-lifecycle.
Any disruption to communications could directly impact research, clinical operations, and regulatory workflows.
!Key Challenges
Legacy Infrastructure
Exchange 2010 & Lync 2010 approaching end-of-support across 3 regions.
Massive Scale Migration
60,000 mailboxes averaging 520 MB — phased, zero-data-loss migration required.
Federated Partners
25–30 federated partner organizations with TLS-secured connectivity.
Identity Integration
FIM identity integration required 6+ months prior to any user migration.
Enterprise Voice
29,000+ UM users with enterprise voice — zero service interruption acceptable.
Compliance Mandates
RPO 30 min & RTO 8 hours mandated by compliance team.
Insyto's Approach
Five Phases, One Seamless Transformation
Business Outcomes
Mailboxes migrated with zero data loss across US, EMEA, and APAC
Recovery Point Objective met — RTO 8 hours maintained throughout
UM users transitioned with enterprise voice & video conferencing
Reduction in manual effort via zero-touch tooling & automation
US, EMEA & APAC — Active/Active HA with site resiliency
No high-severity incidents from month 6 onward
"The complexity of migrating 60,000 users across three regions — with enterprise voice, federated partners, and a live research environment — required a partner who understood not just Microsoft technology, but pharmaceutical-grade operational risk."
— IT Director, Global Pharmaceutical Enterprise
Key Takeaway
Enterprise-scale M365 migrations in regulated industries demand zone-based execution, zero-touch automation, and pharmaceutical-grade risk management — not just technical migration skills.
