This article summarizes what's supported when you use the Azure Site Recovery service to replicate Hyper-V VMs managed in System Center Virtual Machine Manager (VMM) clouds to a secondary site. If you want to replicate Hyper-V VMs to Azure, review this support matrix.
Note
You can only replicate to a secondary site when your Hyper-V hosts are managed in VMM clouds.
