Azure Site Recovery: Upgrade to TLS 1.2 or later by November 15, 2021 - for improved security

Published date: September 27, 2021

As  part of Azure-wide initiative towards using TLS 1.2 by default and removing dependencies on older versions, Azure Site Recovery is working towards shifting away from legacy protocols to ensure improved security for your replication data.  Hence, TLS 1.0 and TLS 1.1 will no longer be supported.  These changes are expected to take effect on November 15, 2021. 

To continue using Azure Site Recovery without any interruption, ensure all the resources using the Microsoft Azure Recovery Services (MARS) agent are enabled to use TLS 1.2 or later.  For information on how to take appropriate steps and ensure that your server configuration does not force use legacy protocols, see the detailed steps provided in our public documentation.
