Migration from hybrid active directory & hybrid exchange to cloud-only environment
Is it generally possible to migrate from hybrid active directory & hybrid exchange to a cloud-only environment with Entra ID and Exchange online & NO additional virtual machine in Azure?
One service provider advised against this and said that once a hybrid environment exists, it must be maintained forever.
Background: we want to shut down our data center and outsource everything to the cloud
chrisslroth : It's possible to migrate from Hybrid Active Directory and Hybrid Exchange Setup to Cloud-Only environment (but it also requires a proper discovery of your existing environment to see if there's any road-blocker before migrating the environment to cloud)
Hello chrisslroth
Generally, the implementation of a hybrid deployment is subject to organization requirement as it offers flexible benefit of on-boarding and off-boarding mailboxes as required. However, you could move all mailboxes to the cloud and continue to manage users in the cloud, if that fits into your organization future plan, then decommission your exchange server(s). You could decommission some or all of your exchange servers depending on your use cases. You could find typical scenarios and what to do in the useful article.
