I logged into the esxi host web page and see both the vcsa source and new vm are running (no surprise there since the migration hasn't finished), but the new VM host name is photon-machine. That made me laugh, but I'm not sure where to go from here. I tried opening a console window, but it's also blank. I can ping the temporary address for the new vm, but I can't get into the 5480 page with any web browser.
Resolved. I shut down the first vm that never got the source config, then started over and created another new vm. This time it went all the way through with no problem, so all good.
