Hi Dion,

As far as I know it isn't possible to upgrade a 32bit system to a 64bit 
system.  Yes, the dist-upgrade process can swap out kernels, etc, but 
most of the apps have been compiled to run on a 32bit system...  Just 
upgrading the kernel and some system binaries would still break the 
'system' as a whole...

I think you are better off just starting with a fresh 64 bit installation.

Cheers,
Peter
