As I said before, this is a production server, so downtime is an 
important issue and had to be minimized.
On the other hand, in my country, internet is very expensive, we pay 
US$100 for 128Kbps.
That's the bandwidth I have available on the server, not to mention the 
technology used for wireless, which gave us huge delays, so the 
performance I get is even lower than 128Kbps.
I know that yum could take me to the 4.3 with no problem, except for the 
time that it would have required.
I also know that some versions of you (not the one shipped with 4.1) 
have the option to "download only", that might have help me, that is why 
I went to the option of upgrading via de CDs.
I appriciate the suggestion, but I'm was not asking for that, I'm just 
trying to figure it out, what did happend.
Is CentOS (or RHEL) not upgradeable skipping versions through CD or DVD?
