The safe play is to read the INSTALL, README & CHANGELOG files for tips on upgrading, as well as what changed. "Usually" though, so long as you configure it the same way, ie same install prefix & etc etc (you can get the old info from the config.log, config.nice or some other file in the old source tree if you kept it), you can install one over the other without issue, if you stay within the same major release level. By that I mean most source is released as x.y.z where x = Major, y = Minor, & z = Revision. If that Major number changes then you should probably backup any config files for the app and uninstall it, then install the new version fresh and reference your old config files for setting it back up. Still though, don't just blindly follow that, take the time to read the docs.
