If you uncheck the "format this partition" during the graphical install 
process (I think that happens after you choose which packages you want 
to install), the old partitions will not be reformatted.  So that should 
preserve your old filesystem.  However, keep in mind that the new 
install may overwrite files with similar names and that any lingering 
config files may confuse packages that are installed.

That said, I've managed to do this on a few occasions to preserve the 
/home partition without incidident.
