[CentOS] Migration from 32 to 64 bits

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?
