Upgrading RedHat 7.0 to 7.1 (sorta newbie-ish)

[Syngin]

Hey guys,

Running RH 7.0 at the moment and I'm trying to get Tomcat 4 (for JSP deployment) up (planning on writing a NHF on the install if I finally get it working). I've installed Sun's JDK (Java Development Kit) as required but I noticed that it says it has 'issues' with RH 7 in the README but should work fine with RH 7.1.

My question:

Are inter-version updates available or would I have to snag the entire 7.1 isos and reinstall?

Probably a very newbie-ish question but I don't think I've seen this addressed except on a per app/kernel basis.

From the sounds of things, there are at least 4 known issues I'd have to deal with. :(

Ok, this was a pretty moronic question considering Redhat has the RedHat Network. I guess my point is if I can get something that will update installed apps to the current version all at once without having to do everything on a per app basis.

I did a full install of RH 7 and am cringing at the possibility of having to update everything one at a time. Reinstalling the entire thing is even a worse possibility.
