Hi,

I just did my first cross-cluster live migration via PDM (between two PVE 8.x
clusters, both enrolled in the same PDM instance). It worked, eventually, but I
hit several "obvious in hindsight" prerequisites that aren't all in one place
in the docs.

Posting my checklist here both to share and to ask the community: did I miss
anything? Any other gotcha worth adding?

(checklist coming in the next post — keeping the OP short)
