Received "Action required" mail about spurious "classic storage account" for VM disks

Yesterday, Microsoft sent me (and presumably thousands of other users) an e-mail telling me that I need to migrate our "classic storage account" . However upon closer inspection of the Azure portal, the only such accounts are artifacts of the existence of virtual machine disks, and none of the links in the e-mail provide any meaningful help for that scenario.

In particular:

  • There is no information on how to store virtual machine disks in this new storage management regime.
  • There is no table of how different "classic" virtual machine disk types map to to the new weirdly named concepts and pricing tiers.

The closest thing to an answer is that some old, gobbledygook-filled guides for moving virtual machines from azure classic to azure resource manager stated that there was no direct equivalent, but that migration of the disks would supposedly work because of the continued support for classic storage, which is no help at all now that they are sending out e-mails about ending that feature.

Note that by gobledygook I refer to starting the instructions with a barrage of feature and concept names that make sense only to the Azure team itself, and might mean something different (or nothing at all) in any other company.

    @MsdnUsrSince1994
    I understand you have some VM disks that are using Classic and wish to migrate these to ARM. Please correct me if I am misunderstanding.

    A guide from migrating from Classic to ARM can be found here. The VHD blobs behind the unassociated virtual machine disks will get migrated when the Storage Account is migrated. Your disks will be inside a blob container named vhds. If you wish to create a new disk from these blobs you can do so by using the create a managed disk workflow and setting the source type as Storage blob.

    Hope this helps to clarify. Let us know if you have further questions or run into any issues.

    I am not saying I want to migrate, I am saying that Microsoft demands that I migrate the company VM disks, but gives no meaningful details, not even the names of objects affected or a link to a relevant migration procedure.

    Also, the disks are not unattached, they are the system disks of running VMs created before the year 2020 and routinely maintained using with rolling upgrades of installed software.
