In their own words
CodeTwo Exchange Migration
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.
Stellar Migrator for Exchange
Stellar Migrator for Exchange moves mailboxes among Exchange Server and Microsoft 365 environments, including transfers between Microsoft 365 tenants. It supports primary, shared, and archive mailboxes as well as public folders, and can run cutover, staged, or hybrid migrations all at once or in batches. Delta migration transfers new or changed data after an initial move. Up to 10 mailboxes and their items can be migrated simultaneously. Users can match mailboxes automatically or map them manually, including with a CSV file, select folders such as email, contacts, calendars, tasks, notes, and journals, and filter mail by date range. Failed or incomplete migrations can be rerun, with automatic retries set from 1 to 5 attempts. It runs on Windows and requires at least 8 GB of memory. The free trial covers 2 mailboxes and includes all migration capabilities; Mailbox Pricing is $250, paid once, billed $10 Per Mailbox, with quantity selected on the page and one license per source mailbox.
