Migrating from RH9 Legacy to CentOS 3

Sounds reasonable.

Should work fine.  Sometimes you will find a dependency issue to work
around.  Often that means removing the old package.  Sometimes it might
mean changing yum's "exactarch=1" to "exactarch=0" to get around a
dependency issue caused by architecture changes (from i386 to noarch
or vise-versa, or from 32 bit to 64 bit, etc).

Generally it runs smoothly, but occassionally some thought must be put
into resolving some dependency issue...

One thing I don't see mentioned much.  First, do a "yum update" or
"yum upgrade" on the RHL 9 repo.  Then do a "yum clean" to free
up disk space.  Then do your yum upgrade to Centos.  Otherwise, you
will have your old RHL yum cache taking up a lot of space...
