I am working with Ubuntu for quite a while (now 10.4 / 32bit).
As I have a 64-bit processor, I'd like to try a 64 OS.
You find enough meanings on the net about "why" and "why not" to change over to an 64-bit OS.
However, you don't find a lot about HOW to do it preserving as much as applications, settings and data from the old 32-bit system.
In short, what is the best way to upgrade your OS to 64-bit ??
Any comments are welcome...
