You'll have to do a new install with a 64 bit install medium in order to switch to 64 bit. <div class="gmail_quote">On Apr 12, 2015 9:37 PM, "Bill Vance" <<a href="mailto:kbun@xpresso.seaslug.org">kbun@xpresso.seaslug.org</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Howdy; Well, it looks like my long awaited hardware upgrade will soon be happening, and thus an upgrade to 14.04, as well. The question I have now, though, is this: The old box was 32 bit, and the new stuffings will be 64 bit. Is there a way to tell the upgrade mechanism to switch to 64 bit, or will I need to go to an install disk? No big deal either way, but I'd rather not waste my time if the disk is required.
