Cloudiway Mailbox Migration Tool is an enterprise software platform that automates the migration of email data between different mail systems. **Supported Sources:** Google Workspace (Gmail), Microsoft Exchange (on-premises and Online), Zimbra, Lotus Notes/Domino, and IMAP servers. **Supported Destinations:** Microsoft 365 and Google Workspace. **Data Types Migrated:** Emails, folder structure, contacts, calendars, secondary calendars, shared mailboxes, litigation hold (Office 365/Exchange), archives, inbox rules, tasks, notes, permissions, rooms & equipment, and distribution lists. Coverage varies by source platform. **Migration Process:** The platform follows a four-stage workflow: discovery & assessment, configuration & pilot testing, bulk migration with parallel processing, and delta sync with cutover. Delta sync allows users to continue sending and receiving emails throughout migration with no downtime. **Security & Compliance:** Uses OAuth 2.0 authentication (no passwords stored), TLS 1.2+ encryption in transit, and is compliant with GDPR, SOC 2, and HIPAA. Email content is not stored on Cloudiway servers — data flows directly between source and destination. **Licensing:** Per-mailbox licensing model with volume discounts. A free trial is available for migrating test mailboxes.
