Updating your Azure Site Recovery On-Premises components

Between two on-premises VMM sites

Download the latest update rollup for Microsoft Azure Site Recovery Provider.
Install Update Rollup first on the on-premises VMM server that's managing the recovery site.
After the recovery site is updated, install Update Rollup on the VMM server that's managing the primary site.

Note If the VMM is a Highly Available VMM (Clustered VMM), make sure that you install the upgrade on all nodes of the cluster where the VMM service is installed.

Between an on-premises VMM site and Azure

Download Update Rollup for Microsoft Azure Site Recovery Provider.
Install Update Rollup on the on-premises VMM server.
Install the latest MARS agent on all Hyper-V hosts.

Note If your VMM is a Highly Available VMM (Clustered VMM), make sure that you install the upgrade on all nodes of the cluster where the VMM service is installed.

Between an on-premises Hyper-V site and Azure

Download Update Rollup for Microsoft Azure Site Recovery Provider..
Install the provider on each node of the Hyper-V servers that you have registered in Azure Site Recovery.

Note If your Hyper-V is a Host Clustered Hyper-V server, make sure that you install the upgrade on all nodes of the cluster

Between an on-premises VMware or physical site to Azure

Update your on-premises management server by downloading Microsoft Azure Site Recovery Unified Setup. This is the server that has the Configuration server and Process server roles.
If you have scale-out process servers, update them next by using Microsoft Azure Site Recovery Unified Setup.
Go to the Azure portal > Protected Items > Replicated Items page. Select a VM on this page. Select the Update Agent button that appears at the bottom of the page for each VM. This updates the Mobility Service Agent on all protected VMs.

A restart is recommended after every upgrade of Mobility agent to make sure that all the latest changes are loaded on the source computer. However, this step is not mandatory. If the difference between agent version during the last restart and the current version is greater than 4, a restart is mandatory. Refer to the following table for a detailed explanation.

Agent version during last restart	Upgrading to version	Is restart mandatory?
9.16	9.18	Not mandatory
9.16	9.19	Not mandatory
9.16	9.20	Not mandatory
9.16	9.21	Yes. First upgrade to version 9.20, then restart before upgrading to version 9.21 because the difference between the versions (9.16 where the last restart was performed and the target version 9.21) is greater than 4 versions.
