By definition, an "upgrade" (as opposed to a clean installation)
means that all data, programs, etc. are kept intact.
However there are no guarantees that it always works perfectly.
However unlikely, it's always possible that something might go
wrong. For that reason it's prudent to be sure you have a backup
of anything you can't afford to lose before beginning.
But are you sure you want to do this? Are you aware that XP Home
and Professional are identical except that Professional includes
a few features (mostly related to security and networking)
missing from Home? Most home users don't need and would never use
these extra features and will see no benefits by upgrading.
