[plug] 64 Bit Upgrade of Ubuntu

[Dion Curchin]

Hi, Google isn't being all that helpful today.

So. Does anyone know if its possible to upgrade Ubuntu Natty from 32 Bit 
to 64 Bit? All the google results suggest that it can't be done and that 
a clean install is required. However all the results seem to be old, 
like 2008 kind of old.

I don't really get why such an upgrade can't be done though. The 
dist-upgrade process replaces the kernel, system binaries and drivers, 
so why can't that be done and simply replace those things for the latest 
version in 64 bit?

Any thoughts smart people?

Cheers.
Dion.
