Downgrading the 2.3.1(openpkg)-hosting Debian System?

[Johannes Graumann]

Hello,

Background:
When setting up the vserver I rent, I decided in a typical "I got to much 
time on my hands"-move to go with Debian testing rather than stable, as 
proposed (and infact provided) by the hosting company. Now testing is 
upgrading libc and as a result requires a kernel >=2.6.26, which the hosting 
outfit won 't provide (yet) - we're at 2.6.18. As a result I'm stuck for all 
upgrades of the underlying system and am looking how to remedy the 
situation.

1) Please excuse the naiveté of this question, but is it possible to just 
migrate an openpkg-compiled /kolab directory (and the corresponding 
/etc/init.d/kolab file) from the existing testing to a "fresh" Debian Stable 
instance?

2) If there is such a migration path: can that be combined with switching to 
a *.deb based kolab infrastructure and is there a proper repository to 
integrate into my /etc/apt/sources?

Thank you for any hint you might be able to give.

Cheers, Joh
