Hands-on migration plan for ~10,000 Hyper V VMs with concrete results and tooling: cold shutdown, copy VHDX, convert root disk with v2v and qemu-img, convert data disks with qemu-img, add first‑boot scripts for NIC renaming and Windows cleanup, upload via CDI and virtctl, and orchestrate everything with Ansible over WinRM. Covers Windows Server 2019/2022, Linux RHEL8, 70 appliances, TPM and PVC sizing workarounds, E1000 fallback for appliances, and typical 2–3 reboots before network comes up.
