On the general level, most practical unix administration differs.
There is not much in common between the tools on HP/UX, Solaris, AIX
and OSF/1 what is this called at the moment? Digital Unix?
Anyway... :-)

Some of them share the administration structure - this is where you'll
notice the difference between System V and BSD (/etc/rc.d/ directories
versus /etc/rc.local the file), but the administrative tools are
different.

What you should try to understand is the structure of a unix system.
This is the same, even if the tools and files have different names and
behaviour.

Network administration requires the same understanding no matter which
OS you need to use.  If you understand ethernets, routing and IP
interface configuration, it does not matter which tool you use to
configure it.  (But it seems like everyone is using Perl in the
end. :-)

It is not easy to learn what is different and what stays the same.
Even after working with 8 different Unix operating system the last
seven years, I still get surprised on how many good ways there is to
solve the same problem. :-)
