In their own words
CloudM Migrate
CloudM Migrate moves users, mail, files and shared data to Google Workspace or Microsoft 365. It handles mailboxes, folders, attachments, contacts and calendars, and supports more than 20 source platforms, including on-premises servers, Zimbra, Box and Dropbox. Before migration, discovery scans mailbox volumes, item counts, folder depth and potential issues. Pilot, bulk and delta passes support phased moves and data catch-up through cutover; reporting, audit logs and service logs help track progress and diagnose issues. Customers can choose CloudM-hosted deployment or run Migrate in their own infrastructure. In self-hosted deployments, migration content stays within customer-controlled infrastructure, is encrypted in transit, and temporary files use AES-256 encryption. Each license includes a 12-month migration license and unlimited catch-up runs during that period. Document version history is supported for Microsoft 365 destinations, while Google Workspace receives only the latest document version. CloudM offers serviced migration options, including planning, execution, go-live and post-migration support. Pricing is on request, with license options priced per user or data volume and serviced migration available by quote.
imapsync
imapsync is an IMAP transfer tool for migrating or backing up mailbox accounts. Its command-line software makes incremental, recursive transfers, and a stopped transfer can be restarted without generating duplicates. The software runs on Windows, Mac OS X and Linux, with listed compatibility including Gmail, Office 365, Exchange, Dovecot and Zimbra. The online service offers free mailbox syncs below 3 GB; buying provides unlimited syncs of any size. Buyers also receive a visual interface for installation on a Linux server, though that interface does not yet work on Windows. Staged and tenant-to-tenant moves are supported, including for Microsoft 365 and Google Workspace. The software-only plan is €72 as a one-time purchase; professional support is €144, paid once, as is the Imapsync + support plan. There is no trial version, and purchases carry a 30-day money-back guarantee. The tool cannot migrate contacts or calendars, maintain two-way synchronization between active accounts, or transfer messages to or from a local directory.
