Redhat 8 to 9

[Michael Kratz]

I've got a redhat 8 server, and out of interest I configured yum to use the
redhat 9 repositories, then toyed with yum update <insert popular package>
(i.e. apache, sendmail, etc) what is interesting is that with some of these
theres very few dependencies to do the upgrade. (i.e. dependency for
sendmail was tcpwrappers, and thats it)

My question is, is this a bad thing to do, and would it really break
anything by upgrading some things to the Redhat 9 versions?
