Hello @Phil Marland - Thanks for reaching out.
We don't support moving a VM. But we support importing a VM (which is a copy really).
Here is the doc reference for the same : Import-virtual-machines-from-another-lab
You cannot de-link the DTL VM so that it would become a Compute VM but you can always use the SIG route to create the compute VM which is similar to the current state of the specific DTL VM.
I hope this information helps.
If the above response helped please "Accept as Answer" and "Upvote" the same.
