[CentOS] Re: question about updates with centos 3.x / Upgrade to 3.5 for the updates or reinstall all servers with centos 3 ?

Exactly: 3.5 is the updates for 3.4 which was the updates for 3.3 etc.
It's just that The Upstream Provider from time to time provides not only 
security updates but bugfixes and enhancements, while security updates are 
released immediately, the remaining two categories are released in a 
bigger batch.  These bigger batches result in a lot of packages being 
updated and thus make sense for new iso's to be issued for downloading 
(which incorporate all the latest fixes, both security and bug and 
enhancements).  Such a new set of iso's gets a new number (ie. the just 
released 4.1) even though what it is is just 4.0 with all then-current 
updates.

So unless you have hardcoded the '3.3' or whatever (instead of just '3') 
into some paths in your yum/apt/up2date configuration files they should
work normally and provide a lot of updated packages.
