I’ve read about the public preview support for Premium Managed Disk. Is there currently or will be support for Premium Unmanaged Disk.
You can fail over to Azure Premium managed disk with 7.0 but cannot fail back without downtime conversion. Whenever 7.5 for Azure is released, it will support Managed disk for both failover and failback.
Unmanaged disks are no longer supported in Zerto 7.5.
