Is there a way to upgrade an existing 32bit-system to a 64-bit-system?
I run 32-bit systems on 64-bit-hardware and I think its time to get a first look on 64bit, so I could check it out. Additionally I have 8Gigs on several machines, which still is a problem with 32-bit to me. (see my other post about PAE-kernel).
I run 7.10 and 8.04-machines, so the question applies to both ubuntu-versions.
Additionally: How do I find out if my hardware is 64bit-able if I'm not sure. I know for my Xeon-machines, but on two older machines, I am not sure:
processor : 1
vendor_id : GenuineIntel
cpu family : 6
model : 15
model name : Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz
and (very unlikely)
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 95
model name : AMD Sempron(tm) Processor 3200+
