+
+	<answer>
+	  <para>By all means!  While a recent system will run with
+	    software compiled under an older release, you will end up with
+	    things randomly crashing and failing to work once you start
+	    installing other ports or updating a portion of what you
+	    already have.</para>
+
+	  <para>When the system is upgraded, various shared libraries,
+	    loadable modules, and other parts of the system will be
+	    replaced with newer versions.  Applications linked against
+	    the older versions may fail to start or, in other cases,
+	    fail to function properly.</para>
