Is it possible to "upgrade" from a 32bit to a 64bit installation?

I would like to know if it is possible to upgrade from 32 bit to 64 bit. Say currently I am using 11.04 32 bit, then come October could I upgrade to 11.10 64 bit? Not a fresh install, or separate install. It is possible? If not what would be the recommended way to go about this?

Thank you for your time and answers

I think this is not possible. You would have to reinstall the whole system, because you need to "change" all packages in your system from 32-bit binaries to 64-bit binaries.

Why do you need a 64-bit system? If you have 4 GB RAM (or more), you can just install PAE kernel (package linux-generic-pae). PAE supports up to 64 GB of RAM.
