Hello to all,
currently I have CentOS 6.4 32 bit, very simple setup on my notebook, I want to migrate it from 32 to 64 bits cause I want to play with some VMs etc etc.
Do you have some suggestions on how to do backup of folders (mainly I have 1 user) or just copy the user folder and stop?

Hmmm... we have 32bit CentOS 6.3 running both 32bit and 64bit VirtualBox VMs just fine.
Yes, if you want to use KVM you'd need a 64-bit install, but for VirtualBox or VMware Player it should only depend on the CPU capability, not the host OS.
While technically true, I can't imagine wanting to do much with VMs without the extra RAM space afforded by 64 bit O/S. Really, 2 (ok, 3) GB of RAM is *not enough* to do serious work. I'd strongly suggest starting with at least 8 GB of RAM. You can do it with the 2 or so that you have, but I wanted to scream with 2 GB using VirtualBox for Windows compatibility testing.
8 GB lets me run a host OS (Fedora) and 2 VMs without too much trouble. 3 VMs starts to slow down noticeably, no matter how I tweak the memory split.
