Is there a way to upgrade ROOT from previous version?

Dear all,
For now, every time I want to upgrade ROOT, i have to delete the current ROOT folder and reinstall it completely, is there an easy way to upgrade root from the current version?
Thanks

Starting from a fresh build is the best way for sure. If you start from sources, the compilation takes only some minutes after all.
