| I would do this in small steps, e.g. first migrate to the new machine / OS:
| - - Get Python 2.3.x installed on the OS/X server.
| - - Build the latest Zope 2.8.* on that server.
| - - Install and test products there in the same versions you now use.
| - - Copy your old database over and test.
| then upgrade the software stack:
| - - Move carefully through the Zope releases (I would to 2.9, 2.10, and'
| 2.12), upgrading Python as needed to stay on a supported version.
| - - Check for upgrades to the products, and their compatibility with
| Zope versions. Test them, and your site. after each upgrade.
The move from 2.9 to 2.10 is likely to be the most painful part in
terms of legacy Zope apps. A lot of products will break on 2.10
