Cloudiway Mailbox Migration Tool vs Stellar Migrator for Exchange

Cloudiway Mailbox Migration Tool is a web service for moving mailbox data from supported systems into Microsoft 365 or Google Workspace. Sources include Google Workspace, Microsoft Exchange on-premises and Online, Zimbra, Lotus Notes/Domino, and IMAP servers. It transfers emails, contacts, calendars, tasks, notes, inbox rules, shared mailboxes, distribution lists, and archives. Delta sync keeps users working during migration and captures changes made before cutover. Automated provisioning, folder mapping, error handling, and date-range, folder, and content filters provide migration controls. A real-time dashboard shows progress, statistics, and issues, while parallel processing can handle thousands of mailboxes simultaneously. The service supports OAuth 2.0 on supported platforms, TLS 1.3 in transit, and AES-256 at rest. Cloudiway lists ISO 27001:2022, GDPR compliance, Microsoft SSPA certification, and HIPAA readiness. Migration data is automatically purged afterward, with European and EU-only processing options available on request. Plans start at $570, paid once, and a free trial uses real data without requiring a credit card.
