What you feed your horse is going to depend on her new living situation as well as how much work she is getting, and her condition.
First you need to look at if she is being pastured or stabled, or a mix. If she is is pastured then you need to consider the amount of grass and it's quality that is available to her, it can also change in different seasons.
An example is my horse who is on approx. 10 acres with some other horses, 24/7. Most of the year he is fine just on grass. I supplement the grass with small feedings for vitamins and minerals. However this winter there was not a lot of rain and early frosts so he is now needing to be fed hay regularly, which I go and feed him myself daily. If I had him stabled part of the day/night he would be having pretty much as much grass hay as he wanted during the evenings, and if he had a private paddock I'd also be giving him free choice hay.
Consider where you plan to keep the horse. If its full care then feeding may be taken care of for you, and they might have hay in the pastures etc. If you're keeping your horse on self care you'll need to be more critical of the situation you're going into, what feed is available etc.
He's in light work, but if I was riding him a lot I would be more concerned with a more concentrated feed.
