You can't; what I meant is that I'd prefer this:
 * old server Jaunty 32 bit => new server with Jaunty 32 bit clone =>
clean 64 bit Lucid installation

over what you had said:
 * old server Jaunty 32 bit => clean 64 bit Karmic installation on the
new server => upgrade to 64 bit Lucid.

Erm, all of the above?
If you install this kernel in Jaunty/Karmic, then you can access more
than 4 Gb of RAM while having 32 bit systems/OS:
http://packages.ubuntu.com/karmic/linux-server

So you can do that either in the old or the new server.
