I can second this; I have a few boxes that I have upgraded from 5.7 to 7.3; minimal issues. Upgrades just seem to work. (One warning is some really old versions sized /usr or /usr/local (I think) too small for some of the newer versions, so I had to some clean up by hand to make space because the kernel relinking after each boot takes a decent amount of disk space that those older smaller partition have trouble handling.) One can also do "pkg_add -vnUu" before upgrading to know what will be done (v=verbose, n=don't install, say what will be done, U=update dependencies). One can also use sysclean to help clean up old libraries and shared libraries left behind to get more disk space back. Also, run "pkg_delete -a" to remove unused dependencies.
