9000+ Mailboxes Migrated with Zero Disruption

A logistics company that suffered operational fatigue and business losses due to missed alerts, dismissed notifications and severe performance deficits migrated 9,000+ mailboxes to Sarv Workspace. They signed up with one non-negotiable: no disruption to daily operations.

Workspace Migration for Large Enterprises - in numbers

• ~9,200 mailboxes migrated
• 160+ hubs & regional offices covered
• 3 migration phases
• 99.98% mail flow continuity during cutover

The Challenges Faced By Logistics Company

Before partnering with Sarv Workspace

• Recurring server downtime during business hours delayed dispatch confirmations across 20+ locations
• 9,200 mailboxes strained the old platform — delayed mail, login failures, webmail issues during peak hours
• Shipment-exception alerts silently dropped, with no way for IT to catch failures before they hit operations
• No visibility during outages; IT was stuck troubleshooting reactively instead of running a stable workplace platform

What Sarv Workspace Delivered?

Wave-based migration: mailboxes moved in regional waves during off-peak hours

Data integrity checks: every wave verified (emails, folders, calendars, contacts) before sign-off

Staged authentication: new credentials ran alongside old ones, no access interruption

Controlled webmail routing: switched hub by hub, not all at once

Dual-delivery protection: mail mirrored between old and new environments during validation

Continuous monitoring: automated mail-flow tests with real-time alerts

Conclusion

Migrating 9,200 mailboxes across 160+ hubs is the kind of project that usually comes with at least a few rough days. This one didn't. That's the difference Sarv Workspace's approach to large-scale migration makes. The benefits of in-house teams, made in India servers, technology capability and infrastructure adds to our strengths and therefore customer benefits.

Wave-based sequencing, SSO-aware coordination, and per-wave rollback meant no single mistake could cascade into an organization-wide problem. For a logistics company where a dropped shipment alert has real downstream cost, Sarv Workspace proved to be a perfect partner.

Our support team not only aced communication and project management but we could handle enterprise-scale migration without putting anything at all at risk.
