Peonies are one of the longest lived perennials. It is not uncommon for peonies to live fifty to one hundred years without ever having to be divided, provided they are grown in rich organic soil with good drainage and a site with eight or more hours of sunlight. However, a peony planted next to a young tree will soon become shaded and have to be moved. Our experience has been that older (5 years +) bushes don't transplant well without being divided first. A short video on how to divide peonies will be posted soon.
