 ## Prerequisites
 
 >[!Note]
->If VMM server is running on Windows Server 2016 machine, ensure that [Open SSH package](https://github.com/PowerShell/Win32-OpenSSH/releases) is installed. 
+>- If VMM server is running on Windows Server 2016 machine, ensure that [Open SSH package](https://github.com/PowerShell/Win32-OpenSSH/releases) is installed. 
+>- If you deploy an older version of appliance (version lesser than 0.2.25), Arc operation fails with the error *Appliance cluster is not deployed with AAD authentication*. To fix this issue, download the latest version of the onboarding script and deploy the resource bridge again.
 
 | **Requirement** | **Details** |
 | --- | --- |
 | **Azure** | An Azure subscription  <br/><br/> A resource group in the above subscription where you have the *Owner/Contributor* role. |
-| **SCVMM** | You need an SCVMM management server running version 2016 or later.<br/><br/> A private cloud that has at least one cluster with minimum free capacity of 16 GB of RAM, 4 vCPUs with 100 GB of free disk space. <br/><br/> A VM network with internet access, directly or through proxy. Appliance VM will be deployed using this VM network.<br/><br/> For dynamic IP allocation to appliance VM, DHCP server is required. For static IP allocation, VMM static IP pool is required. |

 | **SCVMM accounts** | An SCVMM admin account that can perform all administrative actions on all objects that VMM manages. <br/><br/> The user should be part of local administrator account in the SCVMM server. <br/><br/>This will be used for the ongoing operation of Azure Arc-enabled SCVMM as well as the deployment of the Arc Resource bridge VM. |
 | **Workstation** | The workstation will be used to run the helper script.<br/><br/> A Windows/Linux machine that can access both your SCVMM management server and internet, directly or through proxy.<br/><br/> The helper script can be run directly from the VMM server machine as well.<br/><br/> To avoid network latency issues, we recommend executing the helper script directly in the VMM server machine.<br/><br/> Note that when you execute the script from a Linux machine, the deployment takes a bit longer and you may experience performance issues. |
