Secondary RHEL 4 OS Version Install - Possible?

Can anyone tell me if it's possible to put both the x86 32bit and x86_64 version of RHEL 4 on a 64 bit capable system at the same time so that you can use GRUB to select the version you load?

I am currently running RHEL 4.5 x86 32bit and I wanted to move to the RHEL 4.5 x86_64 version. Can I add it to my existing installed OS as a boot time option or do I need to start over clean with RHEL 4.5 x86_64 and reload everything?

Yes it is will need a new system configuration. It is best to have separate root partitions for the 32-bit and 64-bit installations. Sharing the boot and home partitions is acceptable. One need to be careful of updating both versions at the same time.

Of course one could do a full 64-bit installation and have/use a Xen/VMWare 32-bit or 64-bit Virtual Machine also.
