I just did a server upgrade new MB/CPU/RAM and moved from RH 7.2 (I know 
it was old) to CentOS 4.4 64 bit and just copied over the /etc/passwd 
group gshadow and shadow and no problems. Of course I had to merge them 
somewhat for system users but that was pretty easy. You could always 
take the old files and put them in /etc but of course you would need to 
keep the new ones made by CentOS and add in any uses the system needs. 
This is what I did. no need to convert anything.. they're both RH based 
systems. Of course, YMMV.
