Case Study: ODM Computers achieves secure, zero‑downtime migration of 3,500 mailboxes from Office 365 to on‑premises Exchange with BitTitan

ODM Computers migrates 3,500 users from Office 365 to Exchange on-premises

ODM Computers, a leading technology consultant and 2014 Microsoft Partner of the Year in Spain, needed to migrate 3,500 Office 365 mailboxes (mail, calendars, tasks, contacts) for a healthcare customer with strict EU-only PII rules and a hard no‑downtime requirement — all over a single weekend. ODM selected BitTitan (MSPComplete) to meet the security, compliance and timeline constraints.

Using BitTitan’s MSPComplete platform and accessible support, ODM performed incremental pre-migrations two weeks ahead and completed the full cutover of 3,500 users in one weekend with no downtime, while ensuring data never left BitTitan servers in the European region. The migration was successful, the customer was pleased, and ODM plans to migrate an additional 6,000 seats, strengthening the customer relationship and demonstrating BitTitan’s measurable impact.
