I have been using rsync for years now to sync directories around on VMware ESXi systems with great success.

Usually when upgrading to new physical machines, I synced the things to migrate to a big disk, then physically mounted that disk in a new machine.

Not this time: because of an unscheduled event I had to bring up the target machine in a different place before I could assemble the data on the big disk.

But since there was a network tunnel between the networks of both ESXi machines, I wanted to transfer over ssh: a thing I had done numerous times between various Linux and unix machines.

The cool thing is that rsync supports remote connections over ssh out of the box. Between ESXi machines, I bumped into this error though:
