Generally Available: Auto-renewal of certificates for on-premises to Azure Site Recovery

Azure Site Recovery has introduced automatic renewal of certificates for on-premises to Azure disaster recovery. Azure Site Recovery uses various components for doing disaster recovery (DR) from on-premises to Azure. Certificates are essential for communication between components and need regular renewal to avoid disruptions in Azure Site Recovery operations (like data replication, etc.). With public preview of Modernized VMWare to Azure disaster recovery announced in August 2021, certificates used for VMWare to Azure disaster recovery will start expiring from August 2024. This new capability ensures automatic renewal of certificates without affecting ongoing replication. For auto-renewal, customers need to ensure mobility agent and components within appliance are updated to the latest version. If certain components are not updated or cannot communicate, automatic renewal may fail leading to appliance health errors or agent health errors. Customers should follow the documentation to manually renew the certificates if needed.
