How to move VMSS from using Unmanaged to Managed disk

    Question

  • Hi,

    We wanted to know if there is any documentations around moving VMSS from using Storage Account disks to Managed Disk.
    For an VM i understand we have a cmdlet which enables this migration - ConvertTo-AzVMManagedDisk and dont see an equivalent for VMSS.

    Please help.

    Thanks,
    Pradebban Raja

  • Hi Pradebban,

    convert the VHD disk you are using for your VMSS from unmanaged to managed by following http://www.aidanfinn.com/?p=20441 and then use it to configure the VMSS

  • You just need to update the Scale Set to use the Managed disk rather than VHD as the source. You can do this with an ARM template or PowerShell.
