How to Change AS server channel to ES channel

I can tell you that the 3 rpms that change between RHEL 4 AS and RHEL 4 ES 
are:

redhat-release
anaconda-product
comps

I don't know if you would have to remove/add the AS machine from RHN or 
not, or if replacing redhat-release will make it seem obvious to RHN or 
not that it has changed.

HTH,
