What Can Priasoft Migrate Between Exchange and Microsoft 365?

Updated

Priasoft migrates Exchange mailboxes, public folders, permissions, Outlook profiles, and PST files across Microsoft 365 (Office 365), on-premises, and hybrid environments. Its migration suite also covers tenant-to-tenant moves and legacy systems, with support listed from Exchange 2010 through Exchange Online. If your project involves any of those objects or environment combinations, Priasoft's tooling is designed to address it; if you need to migrate non-Exchange workloads (for example, SharePoint or Teams content), that falls outside what the site describes.

Migration objects Priasoft covers

According to Priasoft's product descriptions, the following items can be migrated:

Object What the site says
Exchange mailboxes Migrate mailboxes across Office 365, on-premises, or hybrid environments
Public folders Public folder migration and management, including analysis and hierarchy optimization
Permissions Migrated alongside mailboxes and public folders
Outlook profiles Migrated as part of the suite's supported objects
PST files Migrated across the same environment types

The site groups these under its Exchange and Office 365 migration offering, which it describes as handling "complex Exchange and Office 365 migration" needs.

Environment combinations supported

Priasoft states its tools work across:

  • On-premises to Office 365 — the classic hybrid or cutover migration path.
  • Tenant-to-tenant — moving between Microsoft 365 tenants.
  • Hybrid environments — where on-premises and cloud coexist.
  • Legacy systems — the site lists support from Exchange 2010 through Exchange Online, so older on-premises versions are in scope.

If your source or target falls anywhere in that range, the suite is positioned to cover it. The site does not describe support for non-Microsoft mail systems, so migrations from platforms like Google Workspace or Lotus Notes aren't addressed in the available material.

Risk-reduction features worth knowing

Two capabilities stand out for planning a migration:

  • Dry-run modeling — the site says this lets you "pinpoint potential issues in advance," so you can test a migration before committing to the real cutover.
  • Incremental backfill — described as a way to "maintain business continuity," meaning you can sync changes in stages rather than requiring a single downtime window.

The site also claims "full visibility and control over the entire process from start to finish," though the specific reporting or monitoring interfaces aren't detailed in the available page content.

How to decide if Priasoft fits your scenario

Ask three questions:

  1. Are your migration objects on the list? Mailboxes, public folders, permissions, Outlook profiles, and PST files — yes. Anything else, check directly.
  2. Are your environments covered? On-premises, Office 365, hybrid, tenant-to-tenant, and Exchange 2010+ are all named.
  3. Do you need staged cutover? If minimizing downtime matters, the dry-run and incremental backfill features are the relevant ones to evaluate.

The site mentions a free evaluation and pricing as available options, so you can test against your actual environment before committing. For a definitive answer on edge cases — unusual permission models, very large public folder hierarchies, or mixed-version coexistence — request the evaluation and validate with your own data rather than relying on general feature lists.
