Hi Carol,
Congratulations on your new mare! 
You ask a very valid question and it is wise of you to consider the change in her diet. As with any change, it is best to move slowly. If you are able to bring some of the hay that you feed to the current owners, that would be ideal. And once you get her to your home, you can allow her to graze a little more each day until she is out there full time. You may want to consider adding a prebiotic such as Ration Plus to help the bacterial flora adjust to her new diet. The reason we take our time in diet changes is because these microbes need to become used to new feed substances. Ration Plus will just speed up the process and help prevent colic.
Have fun!
All the best,
Dr. Getty
