Exchange 2010 to Microsoft 365 Migration – Recommended Approach and Tools

We recently migrated from Exchange 2010 to Microsoft 365 using EdbMails, and the process was quite straightforward.

A direct migration from Exchange 2010 to Microsoft 365 is possible, so in many cases you don't need an intermediate Exchange upgrade. The exact approach depends on your environment and requirements, but it's worth assessing your current setup before starting.

For mailbox and PST migration, EdbMails worked well for us since it supports migrating Exchange mailboxes and importing PST files into Microsoft 365 from a single platform.

A few recommendations:

Verify Exchange server health before migration.

Test with a few pilot mailboxes first.

Clean up unused mailboxes and old data.

Plan the migration in batches .

The biggest lesson learned was that proper planning and testing made the actual migration much smoother than expected.

Hope this helps.
