If you can take some of the hay he's used to with you that would be great. Tummy upset can happen with different types of hay. This way you can instruct the people that feed to s.l.o.w.l.y introduce the new hay to him.
As for turn out, if it's in a big area that allows him or another horse to get away from the bossy one, they usually figure things out.
Other than feed changes, lots of visits by his person, whom I sure he just adores, will make the changes easier on him.
