Moving from Linux Repository to System Update

[This should have gone before my other email about my bricked server, but it 
looks like I misaddressed it]

Is there anything special I need to do to a server's configuration to move 
it from using the Dell Linux Repository to the Dell System Update?

Or is it just a case of doing

1) wget -q -O - http://linux.dell.com/repo/hardware/dsu/bootstrap.cgi | bash
2) yum install dell-system-update

And then using "dsu" rather than "update_firmware" (among other things)?  I
don't need to remove any old packages, or delete the .repo file?

Under the old system I would do "yum install srvadmin-storageservices 
srvadmin-omcommon -y" to just get the storage bits (and those they depend 
on).  Can I do the same when using DSU?  Or can I only do "yum install 
srvadmin-all" (I assume that's a meta-package)?

Thank you,

Ben
