[CentOS] Migrate from RHAS 4 to CentOS 4.2

I have a SGI Altix 350 (ia64) that came with RHAS 4, but without any  
paid support.  I would like to migrate the server over to CentOS.   
Here is what I've pieced together from some older posts by Johnny,  
can someone confirm this should work?  I know this is somewhat  
covered in the FAQ, although both entries refer to FC or WBEL, which  
already have built-in yum support.

Install the following files:
http://vault.centos.org/4.2/os/ia64/CentOS/RPMS/ 
yum-2.4.0-1.centos4.noarch.rpm
http://vault.centos.org/4.2/os/ia64/CentOS/RPMS/centos- 
release-4-2.1.ia64.rpm
http://vault.centos.org/4.2/os/ia64/CentOS/RPMS/centos- 
yumconf-4-4.3.noarch.rpm

Edit /etc/yum.conf and perform a "yum update".

Thanks,
