MailJerry vs Priasoft Migration Suite for Exchange

MailJerry is a cloud tool for moving email data directly between providers. It transfers messages, folders, drafts, labels, and sent objects, and says it works with all IMAP providers; named services include Gmail, Microsoft 365, Exchange, Yahoo, GMX, and iCloud. Bulk migration can handle multiple mailboxes, with CSV upload available on paid plans. Paid features can synchronize mailboxes, transfer new messages automatically, or back up email on daily, weekly, or monthly schedules. Controls include date-range filtering, bandwidth throttling, migration status details, and automatic reconnection after a server interruption. MailJerry says email data is encrypted, message contents are not readable by the tool, and messages are not stored. It states that its migration tool complies with GDPR. The free plan allows unlimited mailboxes but caps each at 150 MB and concurrent migrations at three; it excludes auto-sync, backup, bulk migration, CSV upload, and date filtering. The monthly plan is $14.90 a month, and the yearly plan is $129.90 a year; both include VAT. Calendar and contact migration are not supported.

Priasoft Migration Suite for Exchange moves Exchange mailboxes between Exchange environments and to Office 365, also called Exchange Online. Listed source versions include Exchange 5.5, 2000, 2003, 2007, 2010, 2013, 2016, and 2019, with some same-forest scenarios dependent on Microsoft mixed-mode support. The suite supports repeatable dry runs that use the same operations while isolating target objects before production. Migration runs on the wire without first copying data through a temporary file. It can capture mailbox folder delegate details and restore resolved permissions in the target environment. Outlook profile update technology supports standard and RPC over HTTP profiles and cached-mode adjustments, while MAPI/HTTP is listed for Office 365 connections. Calendar and contact migration, tenant-to-tenant moves, staged migration, and Microsoft 365 support are listed capabilities. The product runs on Windows and can be self-hosted. A valid license is required to migrate objects, with licensing metered by processed objects; an evaluation license is available by request. Pricing is on request, and a free trial is advertised.
