The first consideration is whether your Vista x64 is Retail or OEM. If it's OEM the EULA does not allow you to transfer it to a new computer. It is married for life to the original computer it was installed on.
If you have a Retail version then the next consideration is whether your x64 is the 1st partition or the 2nd partition. If it's the second partition you should be able to boot into the x86 (32-bit) version and delete the x64 partition. After you do that Vista has the capability to expand the x86 partition to the full drive.
If you have the Retail version and you delete the x64 from the 1st computer you will have to call Microsoft and tell them the situation and activate it on the new computer via telephone.
There are no other tricks to it.
