Upgrade Question

[Bill Vance]

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.

Thanks in advance.

Bill
