If 7.x is running as a server, you can probably replace it with CentOS 5 with
all the same services and not notice the difference. The CIPE vpn is the only
thing I can think of that has been dropped and if you use imap you'll have to
switch to dovecot. There are many new features, but assuming that not needing
them is the reason you haven't upgraded sooner, the real reason to move to
CentOS is that there are regular updates for security and bugfixes that are well
tested to not break existing behavior. If you haven't updated since the
pre-RHEL days, this may come as a shock, but within the long lifespan of a major
RHEL/CentOS release you can 'yum update' (and reboot if you get a new kernel or
library set) and everything just keeps working the same as before or better.
One thing to watch out for is that if you have more than one network interface,
there's a fair change that the 2.6 kernel will detect them in a new order. If
you configure them with the GUI interface the hardware MAC address will be
picked up in the configs to keep them from changing again.
