[BBLISA] Upgrading from RHEL5 32 to 64-bit?

[Brian O'Neill]

"uname -m" should yield a clue. If the output is "x86_64" or possibly 
"amd64" on older kernels, its 64-bit. Pretty much anything else means 
its 32-bit.

I know of no way to upgrade - a fresh install is necessary.

This should be true for all dists.
