In that case, you're not talking upgrade...you're talking patch/update. 
It is important to make the distinction, because based on your use of the
word "upgrade", Anton's response was correct.

To that end...it is extremely important to watch, in the first, place,
just what is being updated when you perform an update (which is what
you're looking to do). Most of the time, you can determine which services
might need a restart based on what you see in the list of packages to be
updated.

It's not, generally, a good idea to simply apply a ton of patches/fixes
without, at the very least, knowing just what patches/fixes you're
applying...just in case you need to roll back.
