[CentOS] yum upgrading

I have boxes on CentOS 4.2 that I want to move to CentOS5.

Are there any problems envisaged in trying to move 4.2->4.3, 4.3->4.4 and 4.4->5.0, using yum upgrade and changing the repositories at each stage?

I guess it is not too good an idea to try it in one step.

Or do I need the CDs?

Can anyone advise?

TIA

Best wishes

John
