Hi,
I did a similar thing.
Put them all together in a separate directory.
su to root
rpm -Uhv *.rpm
That's it
It is actually better to do them all together because rpm will look into the other rpm's it is supposed to install to solve dependency problems. Unless you happen to know the exact individual order in which they should be installed of course...
I did however install the packages from Base first.
Your upgrade is so close to the original that other libs and stuff probably won't bother. If they do, just add their new rpm's to the list.
Cheers,
Jan
