What changes have you seen that affect using CentOS as a server? Sure, 
the GUI has changed over the years to be more like Windows, but most of 
my servers don't even have a GUI installed.  I have servers running 
CentOS 4, 5, 6, and 7.  The only differences I can think of between 4 
and 7 that affect server administration are selinux and systemd.  
Selinux can be easily disabled if you don't want to deal with it.  I 
don't like systemd at the moment, but that's at least partially due to 
only having worked with it for a couple of weeks so far.  The more I use 
it, the more I get used to it.  So far, it seems easy enough to use once 
you figure out the new commands and file locations.
