If you do not have such, I highly recommend it; both for this project and for everything else going forward. I have considered migrating an OS instance from a physical disk to a VM (or vice-versa) a few times, but always decided to do a fresh install on the intended target. I would build a fresh VM, install fresh software, and migrate configuration, data, and services from the old server to the new VM. Additional details include scheduling, network settings, validation, backup, and rollback. David
