CodeTwo Exchange Migration vs SysTools Email Migration Tool

CodeTwo Exchange Migration is a server application for moving mailboxes and public folders into on-premises Exchange Server Subscription Edition. Sources include earlier Exchange versions, Microsoft 365, hosted Exchange and IMAP systems. Exchange Server 2013 and newer can move directly to Subscription Edition. The software supports cross-forest and cross-domain moves, staged and hybrid migrations, and delta passes that copy new items without duplicating migrated ones. IMAP sources include Google Workspace, HCL Notes, Rackspace, Zimbra, Kopano and Kerio Connect. Administrators can schedule jobs, filter by time or folder, choose item types and monitor detailed reports. Installation runs in the customer environment without third-party migration tools or cloud services. Connections are encrypted, and Microsoft 365 uses OAuth 2.0 without storing credentials. Calendar and contact migration are supported; tenant-to-tenant moves are not. A 30-day trial is available, while paid licenses include support and updates.

SysTools Email Migration Tool moves mailbox content between email platforms while retaining folder structure and message details. It can transfer emails, contacts, calendars, documents, and attachments; Office 365, Exchange, and G Suite are listed as example platforms. Users can filter by date range and choose which mailbox categories to transfer. The tool preserves email properties including read status, reply or forward flags, and sent or received timestamps. Bulk migration uses user fetching and CSV templates, with up to 20 transfers running in parallel. Retry and rerun options are available, along with downloadable summary and detailed CSV reports. The product page says transfers do not store data on intermediary servers, and supported Google and Microsoft platforms can use OAuth 2.0. A local database temporarily buffers data so a dropped internet connection can be restored without restarting the operation. The free demo fully migrates mailboxes for two user accounts. The Paid Version is listed at $35, paid once for five users; the page also notes pricing from $7/user.
