Migrating Azure VM from unmanaged to managed disk

Question

Hello,

I am attempting to migrate my Azure VM from unmanaged disk to managed disk and am wondering what steps I should take for a potential backout plan if the migration fails. Additionally, I am unsure how to restore an unmanaged VM from Azure Native Backup, as there is no clear documentation on the process. Should I follow the same procedure as I would for a managed disk backup or are there specific steps to follow?

I have already reviewed this document (https://learn.microsoft.com/en-us/azure/virtual-machines/windows/convert-unmanaged-to-managed-disks) and encountered a few obstacles that need remediation. These include:

1. Available SKU Quota on Subscription in AE region - Quota is available
2. Reversibility of migration - Migration is not reversible
3. DNS entries are custom
4. Ip address allocation - Static allocation
5. VM has a static public IP address
6. Reviewing VM Extensions agent - MDE Extension is in a failed state.
7. The VM is not part of any availability zone or set.

Thanks.
