It is not pointless, some people want to do it.

I would not use it.

To each their own.

The best way to do any major update is to backup your data, install the
OS, bring back your data and make all the newer services (if you are
moving things like databases or web directories, etc.).

Some people want to take shortcuts to this procedure, and with enough
effort, that tool can work.  But to me, there is too much effort and
there are too many older packages left around as clutter, so I would
never do it.

It can be done, however.

Red Hat released this, so we rebuilt it .. that does not mean one should
use it.
