Hi All, I have 2 servers running Red Hat Enterprise 3.0 (both with WHM/cPanel of course). They are both setup as nameservers (ns1 and ns2 respectively). I'm looking at replacing ns1 with a larger/faster server. Here is my question...should I upgrade to Red Hat 4.0? How will RH 4.0 interact with my other RH 3 server? Should I just upgrade both of them at the same time? Thanks a million for any comments.
