Hi, It is posible to do a simple procedure to upgrade a Centos 5.4 32bits (i686) to a Centos 5.4 64bits(x32_64)?

I was thinking about an upgrade or install without formating.

I will have a current backup before doing it.

Any advice/tips is welcome.

I *strongly* doubt it. When you go from 32 to 64 bit systems, you are essentially replacing the kernel and (at least) about 90% of the standard libraries. I am willing to bet that this mandates an installation.

For the record, I've never tried it. When I put CentOS on my machine, I already had a 64-bit CPU and I never seriously considered NOT using the 64-bit install.

HTH.
