Migrate FSLogix Profile from Azure Files to Azure Blob?

We're trying out Azure Blob storage for FSLogix profiles so we can use 100% AAD Auth for our client AVDs.
However, some of our users are currently using Azure Files for their FSLogix profiles.
Does anyone know if there's a way to migrate the profile from AZ Files to AZ Blob?
We tried manually moving the vhd/vhdx  in our non-production environment, but it didn't work.
