How is an older cat going to react to moving into a new place and separation of a sibling

Ive had my cats for well about 10 years n he (kitto) has a sibling (kuma) but now I'm moving out alone n taking him(kitto) because he's closer attached to me then my other cat(kuma) I'm worried he'll get sick because they have been together since they were kittens and especially because it's a whole new environment. Any tips and pointers for both the cats.
