Updating version on Debian Etch (4.0)

[John Moore]

I have nginx 0.5.32 running on a very busy server under Debian Etch. I'd 
like to update this at least to version 0.6.35 (which I have running on 
another server, under Ubuntu 9.04), and I'd like to make the update 
process as undisruptive as possible, with minimal downtime. I want to 
maintain the layout of conf files, logs, etc. Is there some way I can 
use the .deb package from Lenny, or do I have to build from source? Any 
suggestions on smoothing the path would be most welcome.
