Apps4.Pro Migration Manager vs imapsync

Apps4.Pro Migration Manager has no write-up on Specifiction yet; its figures are above.

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.
