Microsoft 365 Migration Guide: Step-by-Step for Businesses

Migrating to Microsoft 365 improves collaboration and security, but the process must be handled carefully to avoid data loss and downtime.

1. Planning Your Migration

Audit your existing environment. Decide whether a cutover, staged, or hybrid migration is best for your organization's size.

2. Data Preparation

Clean up active directory, remove inactive mailboxes, and ensure compliance requirements are met before moving data.

3. Execution and Testing

Run test batches. Update MX records only when you are ready to switch mail flow. Ensure all users have their credentials and MFA setup.
