Install postgresql-upgrade and do "service postgresql upgrade".
More or less ... that's from memory, and I've not looked at that stuff
in nearly a year. Read the README file under /usr/share/doc/postgresql*
to get the correct details. And make a physical backup first, if the
data is that valuable to you.

A bigger question is why you don't have an organized backup plan to
begin with. Especially if you're keeping priceless personal data
on such a bleeding-edge system as Fedora. (I'll omit the blurb
for my former employer's commercial offering, other than to note
that I'm gladly paying their subscription price now that I don't
get it for free. And I keep backups, too ;-))
