I have been needing to upgrade Zimbra on my FC5 server and have not had the time. However now I am having hardware issues on that system and need to move the entire zimbra installation. I am looking at moving this over to OSX on my old mac (just got a new macbook pro) since I have this hardware. How would one go about doing this?

I would do a cold copy of /opt/zimbra if this were a FC5 to FC5 move, however it is a completely different platform.

Thanks for any insight anyone has.
