It has been stated that there's nothing that Hughesnet can do for Jupiter One users, and to be honest there is nothing they can do to move an Ultra plan to Jupiter II.

"It's been a time of a lot of transitions over here, both in the community and with the arrival of Gen 5. We're trying to move as many people off EchoStar 17 to the new satellite to improve service for all. Until then, there's not much more our network engineers can do, they have already performed capacity expansions on multiple beams for those on Gen 4.
Eventually things will settle down and the kinks will be worked out. There's still a lot of work needed behind the scenes just for the community, plus we're also working on other projects to better serve HughesNet subscribers. We trust the long time posters and experts here to educate the community, and hope that newcomers will gain that trust as well. I have hope and confidence, and we'll help them as best we can."
Hughesnet didn't offer to move Legacy Spaceway III daily plans to Jupiter One, they aren't going to move your ultra plan.
