Is there a way to upgrade my 32-bit version of Ubuntu to 64-bit version? I use Ubuntu 9.10.
If there is no simple way, what if I simply copy my home and /etc directories to new installation, will it work?

Unfortunately, like other OS's, there is no 'upgrade path' to do this. You'll almost certainly need to do a reinstall.
As for preserving your data, backing up your home directory would be a good idea along with any other data and should be easily imported into your new installation.
Always backup your data before attempting anything!
