I've been looking into doing the migration from Classic VMs to ARM, and I prepared the migration in order to check out the resulting resources. I aborted so that I could do some final backups, but after aborting the VM will not boot. The portal just says "failed to start Virtual Machine." If I try to re-prepare, it generates an error stating: the Migration of Deployment for the server is in the process of being aborted and cannot be changed until it completes successfully." It's been about 3 hours since I aborted, and the prepared resources appear to be removed from the portal. Any ideas how to get the VM running again?
