Hi all,
we are going to upgarde our Lab server.
[root@labuspdb2 ~]# uname -a
Linux labuspdb2 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:48 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

can you please provide me with document were it tell us with all steps we need to take.

@Admin: if I am missing anything I like you to give me detail if you can.

thanks alot

No, for several reasons. First, you don't actually tell us what version/distro of Linux you're using...it may be CentOS, Scientific, or RHEL, based on the kernel name you posted. You say "10.2.0.4"...and there has NEVER been a version of Linux with that number as of yet. Second, we aren't going to write up an complete upgrade plan for you...we will help with SPECIFIC questions, but can't/won't hand you a custom deployment plan.

Short answer: figure out what services are running on the system now. Back up their config files and relevant data. Install the new services, move the configs back on, and make sure they work. The longer answer is much too long to type out.
Missing much..read the "How to ask a smart question" and "Question Guidelines" links in my posting signature. Which you have been repeatedly been pointed to before:
http://www.linuxquestions.org/questi...er-4175540908/
http://www.linuxquestions.org/questi...gs-4175534793/

as above

that "el5" means you have some version of RHEL5 installed
( or CentOS 5 or Scientific linux 5 or clearos 5 )

on a server the AUTO upgrade of setting the reops to use "5" and NOT the DEFAULT of "5.?" in the URL for the repos
so that a MANUAL upgrade is needed

but the VERY FIRST thing is update

then upgrade to the current in the OLDER legacy support operating system
RHEL 5.11 ( or cent 5.11 or SL 5.11 )

but for anything more than very basic GENERIC information that is easily found in a 5 minute google search
you need to provide information

Thanks for patient answer John,
I am here to ask questions and I appreciate helps.

cat /etc/*-release
Red Hat Enterprise Linux Server release 5.4 (Tikanga)

Yum command does not work, seems server is not registered. I did try to register the server [rhn_register]when I got errr.
wget http://satellite.example.com/pub/RHN...USTED-SSL-CERT
--2015-05-05 12:49:28-- http://satellite.example.com/pub/RHN...USTED-SSL-CERT
Resolving satellite.example.com... failed: Name or service not known.
wget: unable to resolve host address `satellite.example.com'

not sure how nessecary is to have this update at the moment.

Very glad to know you appreciate 'helps', and don't acknowledge the advice you've been given before in two other threads, and here too.
Again, as said, RHEL 5.4 is old and unsupported, and since you're not PAYING FOR RHEL, you cannot upgrade it, period. Your solution is simple: contact Red Hat support, pay for a subscription, and get their support team to help you.

If you don't plan on paying for support, then stop where you are. Back up your data, and do a fresh installation of CentOS 7.x, then reload your backups.
