Hi everyone,
If you have noticed that there is no release of Fedora 19 scientific, then that is because I failed to fix a few problems on time. My sincere apologies for that.
So, to help you upgrade from Fedora 18 Scientific to Fedora 19 scientific, I have written some instructions in my post here [1].
I didn't have any trouble upgrading but that was also due to my overtly simplistic setup i believe.

I hope they are helpful and apologies once again.
Best, Amit.
