Generally available: Large disk support for disaster recovery of Hyper-V VMs using Site Recovery

You can now enable disaster recovery for Hyper-VMs with data disks up to 32 TB in size. This applies to Hyper-V VMs that replicate to a managed disks in any Azure region using Site Recovery. The feature is deployed in all Azure public and government clouds. With this improvement, customers can protect –

• Their machines to managed disks and failback from managed disks. Previously, only failover to managed disk was supported, whereas replication would happen to unmanaged disks only,
• Large OS disks (up to 4 TB in size, whereas only 2 TB sized OS disks for Generation 1 VMs and 300 GB sized OS disks for Generation 2 VMs were supported).
