Main reasons to migrate from RHEL 5.5 to RHEL 6.0
 

Hi everyone! This will be my first post in LQ, and I hope that as soon as possible I will be helping others with their linux issues, but right now I need your help.

I did some research about the main reasons for upgrading from RHEL 5 to 6, but mostly what I found was generic statements. I do understand that there were security fixes, stability improvements, but I couldn't find detailed information about it.

I never migrated a server in a corporate environment. Only tried distros and versions at home. But now I need to tell the bosses why they should upgrade their servers, and I am not too sure what to state.

Below are the Linux distros I am responsible to check if it is worth upgrading (all RHEL based):


CentOS release 5.5 (Final)
Fedora release 12 (Constantine)
Fedora release 14 (Laughlin)
Red Hat Enterprise Linux Server release 5 (Tikanga)
RedHat Enterprise Linux Server release 5.3 (Carthage)
RedHat Enterprise Linux Server release 5.7 (Carthage)
Scientific Linux release 6.0 (Carbon)
Scientific Linux release 6.2 (Carbon)

Taking the opportunity: What you guys take in consideration when thinking about upgrade the kernel?

Sorry for any mistakes in my english....

no real reasons except for newer versions of software

will the OLD programs port to rhel6.3 ?
if not easily then do not upgrade
there is still a few years left on rhel5.8
i WOULD upgrade from 5.5 to 5.8 though ( if possible)

now CentOS IN NOT RED HAT !!!!
in that the SUPPORT is VERY VERY VERY different

centos 5.5 IS UNSUPPORTED !!
and has not had a security update in over a year
REPLACE IT NOW !!!

Fedora 12 and 14 ARE BOTH VERY UNSUPPORTED and using them in a corporate environment aught to be a criminal felony !!!
fedora 12 is 5 versions OUT OF DATE and has NOT had a security update in 2+ years
REPLACE IT TODAY!!!!!!!!!!!

Scientific Linux 6.0 UNSUPPORTED and has NOT had a security update in about a year
REPLACE IT NOW !!!

SL 6.2 is currently supported

While I understand and share your frustration with Linux users and their apparent lack of running anything current it simply does not do to use all-caps words like you do all the time and especially not when talking to new Linux users.

John VV,

thank you so much for your straight answer! I didn't get the part where you said that CentOS is not RHEL, though! Isn't based on it? I really would appreciate if you clarify that to me!

Reading the moderators' post I guess my work isn't the only place to run out-of-date linux, am I right?

Talking about the moderator and the forum, I gotta let it registered that I am impressed with the cooperation and seriousness of this forum! It's really amazing!

See http://www.centos.org/modules/tinyco...index.php?id=3 or http://en.wikipedia.org/wiki/CentOS ?


No, take for instance this post, then count the hours that elapsed between your post and his...


Thanks, nice to hear. We all do our best to keep this a good place for everybody I guess.
