I have a Dell Optiplex 745 which I rescued from<br>
oblivion last year when an office was being cleared out. I hurriedly<br>
installed Xubuntu 16.04 on it and it's been fine.<br>
<br>
It now turns out that I used a USB containing the 32bit distribution<br>
instead of the 64bit, so I wanted to know if there is a way to "upgrade"<br>
in place from a 32bit 16.04 to 64bit 16.04<br>
<br>
The 745 runs a 64bit processor and architecture, from what I have been<br>
able to determine (at least, it boots from the 64bit ISO on a USB stick,<br>
and everything seems to run OK).<br>
<br>
Or do I have to do a from-scratch installation (not a major problem, as<br>
/home is on a separate partition, and most all the important stuff is on<br>
SVN repos).<br>
