Hi anonymous user - Thank you for reaching out!
Azure Migrate is a one-way journey and does not have any Rollback/Failback options. User should perform Test Migrations prior to performing the final cutover to Azure.
If you are planning for DR strategy, Azure site recovery is the best option that Microsoft recommends.
