[Centos] Re: CentOS-2 to CentOS-3 migration

[John Newbigin]

CentOS2 -> CentOS3 is tricky because almost everything needs to be 
upgraded.  Although most things can probably be sorted out, rpm and it's 
dependents, yum and it's dependents (python) and probably glibc will be 
the problems, mainly because they are running at the time you are trying 
to install the new ones.  If anyone tries it, send me the procedure but 
I think it might be easier to reinstall.

There will also be problems with things like printing changing from lpr 
to cups etc.

RedHat do not provide up upgrade option/procedure so I think you can 
take that as an indicator of how well it might work.
