[Zope] from sparc to i386

Hi all! I've an old zope server running 2.6 on an old sparc. We are going to replace it, so I need to move the Zope thing. The problem is that that Zope server is compiled in sparc and I've made some modification to the source code, so I can't just move it on another machine (including the python 2.1 tree) as is. Which are the best options? Recreate the Zope 2.6 installation, python 2.1 installation and replace the Data.fs? TIA :)
