| 13 | +# Deprecation of disaster recovery between customer managed sites (with VMM) using Azure Site Recovery |
| 14 | + |
| 15 | +This article describes the upcoming deprecation plan, the corresponding implications, and the alternative options available for the customers for the following scenario: |
| 16 | + |
| 17 | +DR between customer owned sites managed by System Center Virtual Machine Manager (SCVMM) using Site Recovery |
| 18 | + |
| 19 | +> [!IMPORTANT] |
| 20 | +> Customers are advised to take the remediation steps at the earliest to avoid any disruption to their environment. |
| 21 | +
|
| 22 | +## What changes should you expect? |
| 23 | + |
| 24 | +- Starting November 2019, no new user on-boardings will be allowed for these scenarios. **Existing replications and management operations** including failover, test failover, monitoring etc. **will not be impacted**. |
| 25 | + |
| 26 | +- If you have an existing configuration, you will not be able to register new VMMs. |
| 27 | + |
| 28 | +- Once the scenarios are deprecated unless the customer follows the alternate approaches, the existing replications may get disrupted. Customers won't be able to view, manage, or performs any DR-related operations via the Azure Site Recovery experience in Azure portal. |
| 29 | + |
| 30 | +## Alternatives |
| 31 | + |
| 32 | +Below are the alternatives that the customer can choose from to ensure that their DR strategy is not impacted once the scenario is deprecated. |
| 33 | + |
| 34 | +- Option 1 (Recommended): Choose to [start using Azure as the DR target for VMs on Hyper-V hosts](hyper-v-azure-tutorial.md). |
| 35 | + |
| 36 | + > [!IMPORTANT] |
| 37 | + > Please note that your on-premises environment can still have SCVMMM, but you'll configure ASR with references to only the Hyper-V hosts. |
| 38 | +
|
| 39 | +- Option 2: Choose to continue with site-to-site replication using the underlying [Hyper-V Replica solution](https://docs.microsoft.com/windows-server/virtualization/hyper-v/manage/set-up-hyper-v-replica), but you will be unable to manage DR configurations using Azure Site Recovery in the Azure portal. |
| 40 | + |
| 41 | + |
| 42 | +## Remediation steps |
| 43 | + |
| 44 | +If you are choosing to go with Option 1, please execute the following steps: |
| 45 | + |
| 46 | +1. [Disable protection of all the virtual machines associated with the VMMs](site-recovery-manage-registration-and-protection.md#disable-protection-for-a-hyper-v-virtual-machine-replicating-to-secondary-vmm-server-using-the-system-center-vmm-to-vmm-scenario). Use the **Disable replication and remove** option or run the scripts mentioned to ensure the replication settings on-premises are cleaned up. |
| 47 | + |
| 48 | +2. [Unregister all the VMM servers](site-recovery-manage-registration-and-protection.md#unregister-a-vmm-server) |
| 49 | + |
| 50 | +3. [Prepare Azure resources](tutorial-prepare-azure-for-hyperv.md) for enabling replication of your VMs. |
| 51 | +4. [Prepare on-premises Hyper-V servers](hyper-v-prepare-on-premises-tutorial.md) |
| 52 | + |
| 53 | +> [!IMPORTANT] |
| 54 | +> Please note that you don't need to execute the steps under prepare VMM. |
| 55 | +
|
| 56 | +5. [Set up replication for the VMs](hyper-v-azure-tutorial.md) |
| 57 | +6. Optional but recommended: [Run a DR drill](tutorial-dr-drill-azure.md) |
| 58 | + |
| 59 | +If you are choosing to go with Option 2 of using Hyper-V replica, please execute the following steps: |
| 60 | + |
| 61 | +1. In **Protected Items** > **Replicated Items**, right-click the machine > **Disable replication**. |
| 62 | +2. In **Disable replication**, select **Remove**. |
| 63 | + |
| 64 | + This removes the replicated item from Azure Site Recovery (billing is stopped). Replication configuration on the on-premises virtual machine **will not** be cleaned up. |
| 65 | + |
| 66 | +## Next steps |
| 67 | +Plan for the deprecation and choose an alternate option that's best suited for your infrastructure and business. In case you have any queries regarding this, please reach out to Microsoft Support |
