Hi,

Fabian is also looking into external migrate, posted a initial proof-of-concept
last week[0]. The currently planned design is roughly:

* having "remotes", which can be any nodes, or a whole cluster
* we want to use the new API Token mechanisms for remotes - this allows
  nice integration where one can also revoke access from another node to
  theirs.
* migration tunnel will for use WebSocket for secure data transfer, this
  allows to do a HTTPS request over API then switch protocol (i.e., what
  HTTP/2 would get us with multiplexing but not as nice)

We may naturally still want to see if some patches of the split up make
sense to apply now.

Just that you know, not that you invest too much time in this now :-)
