Secure, fast and flexible mail migration with no downtime

Migrating mail from one Office 365 tenant to another should be simple, and Cloudiway’s migration suite ensures that it is. The mail migration component is built on Azure, ensuring a secure process from start to finish. All mails are copied directly to your target tenant, so Cloudiway never takes a copy of your mailbox data, improving security even further.

On the strength of successful experiences over the past 10 years, Cloudiway has developed a robust and flexible platform. We monitor, troubleshoot and manage your migration if needed.

Cloudiway provides a full suite of Office 365 migration tools to cover all your needs, with security and reliability in mind. As well as a flexible approach to how and when mailboxes are migrated, many Cloudiway customers performing an Office 365 migration opt to use mail routing, which allows transferring your domain name without downtime.
