Just run "uname -a" and you will see whether your Linux OS is 32 bit or not.

You need to follow the proper 32bit-64bit apps Tier migration method, because it is the way. This is what Oracle says, and this is the requirement. Your compiler changes, your OS arch changes, you got to compile & configure and you got to install the components that has different installation packages for different architectures.
