Hello anonymous user,
Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question. The document you are referring to was created with agent based migration approach using the Azure Site Recovery P2A approach.
Agent less is application/OS agnostic. You could use agent-less migration apporach as well in case your VMs are running on VMware to migrate them as standalone VMs to azure and follow the post migration steps to reconfigure cluster accordingly
Important steps:
prepare-source-machines
create-load-balancer
reconfigure-cluster
