difference between packages for 32 bit and 64 bit

[Tapas Mishra]

Hi,
I am having some confusion.For development work (with kernel
environment) I needed
following packages

bcc bin86 gawk bridge-utils iproute libcurl3 libcurl4-openssl-dev
bzip2 module-init-tools transfig tgif texinfo texlive-latex-base
texlive-latex-recommended texlive-fonts-extra
texlive-fonts-recommended pciutils-dev mercurial build-essential make
gcc libc6-dev zlib1g-dev python python-dev python-twisted
libncurses5-dev patch libvncserver-dev libsdl-dev libjpeg62-dev iasl
libbz2-dev e2fslibs-dev git-core uuid-dev ocaml libx11-dev bison flex


I until now was using them on a 32 bit system.Ubuntu 10.04.
Here I am switching the computer to 64 bit and want to build same
environment how ever my confusion is above packages are approximately
430 Mb and are present in /var/cache/apt/archives on my 32 bit
system.Can I transfer those to my 64 bit system and use or there is a
difference in packages for 32 bit and 64 bit and I should be using a
fresh install on the 64 bit system.
I am not clear with this part.
