Moving a Cyrus installation from Debian Linux to SGI IRIX

[Sander Cox]

Hi,

I recently bought a new server, SGI Origin 200. I've used Cyrus IMAP to 
serve my e-mail for about 3 years now but now I'm changing servers and 
I'm looking for a fast way to transfer my mail from my old server to my 
new one.

What can I do to move the e-mail between the servers mentioned below?

Specs:
Origin 200 IRIX 6.5.17m
Cyrus IMAP v. 2.0.13

Debian Linux 3.0 unstable
Cyrus IMAP v. ??? package cyrus21 (guess that would be 2.1.?)

Regards,
Sander Cox
