Cigati Email Migrator vs Priasoft Migration Suite for Exchange

Cigati Email Migrator transfers PST and OST files and IMAP mailboxes to file formats and email platforms. It supports single and bulk migrations, including importing IMAP accounts in batches from a CSV file. Destinations include PST, PDF, Office 365, IMAP, Google Workspace, and Microsoft 365/Outlook; IMAP migrations also support additional export formats. The product says it preserves folder structure, email properties, attachments, contacts, calendars, and tasks. Users can filter by date range and folders, and PST/OST jobs can also filter by item type. Duplicate detection compares subject, sender, recipient, CC, and body, while an option skips items transferred earlier. Migration reports list successful, skipped, and failed items. PST/OST migrations can export contacts as VCF and calendars as ICS, and split output PST files by a user-defined size. Preview is available for a single selected PST/OST file and for IMAP mailboxes after a successful connection. The free demo transfers only the first 100 emails per folder; the page does not state a time limit. For Microsoft 365 IMAP migration using modern authentication, administrator consent is generally required, though user-level credentials may work where supported. Cigati says its products process data locally.

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.
