What it is

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.
