This one is the migration itself — specifically, how it started: the Terraform and Ansible that stood up the first guest, what running them actually looked like, and the moment the code finally had a home somewhere other than my laptop.</p> <h2 id="rebuild-dont-convert">Rebuild, don&rsquo;t convert</h2> <p>The obvious-sounding plan is to export each VM from XCP-ng and import it into Proxmox. I didn&rsquo;t do that. The two platforms use different disk formats and guest tooling, and — as the last post covered — Proxmox&rsquo;s LXC model means many of these guests stop being full VMs at all. A cross-hypervisor disk conversion would have dragged years of per-VM cruft along with it.</p>
