• Microsoft Azure Site Recovery Unified Setup (VMware to Azure) (version: 9.12.4653.1)

Learn about the details of the issues that are fixed and the prerequisites that should be validated before you install this update.

After you apply this update, the following issues are fixed and the following improvements are included.
 

Microsoft Azure Site Recovery Unified Setup

Improvements

• Configuration server and scale-out process servers can now be installed on Windows 2016 Servers.

Issues fixed

• Performance improvement fixes.
   

Mobility Service

Improvements

• Adds support for Windows Server 2016 (Server Core and Server with Desktop Experience) on VMware virtual machines and physical servers (already supported for Azure virtual machines).
  
  Note Upgrading a protected instance from a different version of Windows Server to Windows Server 2016 is not supported. If a protected instance is upgraded from a different version of Windows Server to Windows Server 2016, you have to disable protection for the instance and protect it again after the upgrade.
• Support for protection of cloned virtual machines. You can now protect cloned virtual machines without affecting the existing replication of the original virtual machines

Issues fixed

• Performance optimizations to avoid delays in Application-consistent recovery point generation.
   

Microsoft Azure Site Recovery (service-side fixes)

Improvements

• Disabled replication is more resilient for Azure-to-Azure region disaster recovery. You can now disable replication without failure even if the source virtual machine is not available.    
• After reprotection is enabled for an Azure VM replication scenario, only the incremental disk changes are transferred from the DR region to the source region instead of a full disk transfer occurring.
• The vCenter discovery process uses an improved discovery algorithm.
• Fixes are made to allow deletion of a vCenter in a disconnected state.

• Azure Site Recovery (ASR) is now built into the Azure virtual machine experience so that you can set up replication in one click for your Azure virtual machines. For more information, see this Microsoft Azure article.

• Support is added for DR between Azure regions for virtual machines that have disk sizes up to 4,095 GB for data disks and 2,048 GB for system disks.

Issues fixed

• The Disable Protection workflow now lets you disable protection even if the Source virtual machine is deleted or not available.
• Performance optimizations allow the transfer of only incremental disk changes from the secondary region to the source region during the Reprotect workflow.
• Performance improvements reduce vCenter discovery time.
• Fixes are made to allow deletion of a vCenter server in a disconnected state.
