EdbMails IMAP Migration Tool vs SysTools Migrator

EdbMails IMAP Migration Tool moves email and folders between IMAP servers, and supports transfers from IMAP to Office 365, Exchange Server or PST, as well as PST to IMAP. The Windows software lists providers including Gmail, GoDaddy, Rackspace, Zoho, Zimbra, IceWarp, cPanel, Yahoo Mail and Outlook.com. Users can choose folders and subfolders and filter mail by date, sender, attachments and AND/OR conditions. The maker says it preserves metadata, headers, folder structure, formatting and language encoding. Multiple mailboxes can be loaded from CSV, and separate installations can run migrations in parallel. Outlook is not required for IMAP-to-IMAP migration or Exchange-to-Office 365 moves. The maker says data and credentials are not stored on its servers and lists OAuth 2.0, TLS, AES 256-bit encryption for locally stored incremental-migration metadata and MFA support. A free trial is available, limited to 30 items from each folder. One-time plans cost 200.00 USD for 100 mailboxes, 299.00 USD for 1000 mailboxes, or 499.00 USD for unlimited mailboxes.

SysTools Migrator transfers mailbox and related data between cloud platforms. It handles email, contacts, calendars, documents, attachments, files, groups, and other listed mailbox data, with routes involving Microsoft 365, Google Workspace, Google Drive, OneDrive, SharePoint, Microsoft Teams, Exchange, Lotus Notes, IMAP, Domino, Zimbra, and Google Vault. Users can choose data categories and date ranges, prioritize users, and monitor progress in real time. Batch and concurrent multi-user migration, reports, and delta migration for data that arrives after an initial transfer are supported. The product runs on Linux and Windows and supports tenant-to-tenant moves. Its product page lists OAuth 2.0 authorization for Office 365, encryption, and ISO 9001:2015 and ISO 27001:2013 certifications. The free version costs nothing and migrates email for 2 user accounts. The paid version costs what you agree with the maker; its license quota is based on user accounts migrated. Free 24x7 support is advertised.
