<div dir="ltr">Dear All: I have installed Edubuntu on this Intel dual-core EMT64 box a few months ago.  At that time, I did not think about the 32bit vs 64bit issue.  Lately, I have the need to do some work in a 64bit environment and then discovered that I have actually installed a 32-bit Edubuntu on this box. (my 'uname -a':  Linux vt-desktop 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux) Is it pretty simple to upgrade to 64 bit edubuntu?  I would not want to reformat my drives since I want to preserve all the current data. Any tips much appreciated. thanks -Vincent </div>
