Overview
This post is more or less notes for moving from CentOS 7.9 to Oracle Linux 7.9 using a script that Oracle kindly provides for the very low low cost of free.
Server Make/Model that is being used in the is article is Dell Inc. PowerEdge T130.
The GitHub repository for the script that converts the CentOS machine into a Oracle Linux machine.
CentOS Stream isn’t supported by this script.
Some Inital Prep
Upgraded the machine using the yum(1) command so CentOS 7 had the
latest packages installed. Made sure to reboot afterwards. This was a
fresh installation of CentOS 7 that isn’t being used in production.
sudo yum upgrade -y
Obtaining the Script
To obtain the script, I used the raw git user content to pull the
centos2ol.sh file from the GitHub repository. This will output it
to the current working directory.
I’ve skimmed the script and it’s pretty well written. Kudos to Oracle.
curl https://raw.githubusercontent.com/oracle/centos2ol/main/centos2ol.sh -o centos2ol.sh
Followed the documentation and continued with running the command for running the script. Note that this assumes that the script has been downloaded into my current directory location.
sudo bash centos2ol.sh
I will provide the output from the script as it was run below and do my best to explain it a little. Though at this time, I’ve just decided to post as is and then promply upate the document with the appropriate data.
Script is checks for required packages needed for it to run. These include the following packages:
- rpm(1)
- yum(1)
- curl(1)
Then the script will check the distribution to make sure it’s supported. If I was running something like CentOS 8 Stream it would exit telling me that it’s not supported. If it’s another unsupported linux distrobution, the result will be the same.
Checks to see if the epel-release package needs to be replaced by the Oracle Linux equivilent. If it’s installed, the script will add it to the list of packages that needs to be replaced.
Script will check /var/run/yum.pid to make sure that yum isn’t
already in use or being used by another program. If it is, script will
exit.
Script will check to see if python2 or python is installed on the OS.
For CentOS 8 it will check the /usr/libexec/platform-python path
to verify this. We’re upgrading from CentOS 7.9 so. The script wont
touch this. This is just provided for general notation.
I will continue to walk through this more. Stay tuned.

Switching default boot kernel to the UEK.
Removing yum cache
Switch complete.
Oracle recommends rebooting this system.
The script recommends a reboot. But, I’ll do that after a few checks.
Post Conversion Testing
This section goes into soem testing to make sure that everything has moved over expectedly.
So far so good. Looks like the oracle-release file has been updated to reflect the new OS version.
cat /etc/oracle-release
Oracle Linux Server release 7.9
Looks like the os-release file is also showing the new OS. All of the information that tells us what the new OS is is available.
cat /etc/os-release
NAME="Oracle Linux Server"
VERSION="7.9"
ID="ol"
ID_LIKE="fedora"
VARIANT="Server"
VARIANT_ID="server"
VERSION_ID="7.9"
PRETTY_NAME="Oracle Linux Server 7.9"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:oracle:linux:7:9:server"
HOME_URL="https://linux.oracle.com/"
BUG_REPORT_URL="https://bugzilla.oracle.com/"
ORACLE_BUGZILLA_PRODUCT="Oracle Linux 7"
ORACLE_BUGZILLA_PRODUCT_VERSION=7.9
ORACLE_SUPPORT_PRODUCT="Oracle Linux"
ORACLE_SUPPORT_PRODUCT_VERSION=7.9
Now I will reboot the server to see if it blows up.
Looks like it did blow up. More information will be provided in the troubleshooting section.
The troubleshooting was successful and the update is booting into the OS consistently across reboots. So, I think everything should be good to go. Though there is more recommended testing on the server before we make that determination.
Using the uname(1) command. I checked the new kernel of the server
and it looks like it successfully installed the UEK 5.4.17 kernel. Which
also confirms that the script worked as expected.
uname -r
5.4.17-2136.305.5.4.el7uek.x86_64
Nothing else to test at the moment. IF there is anythign that comes to mind. I will make sure to update my notes.
Troubleshooting Log
04-06-2022T23:03:00 - No Boot Disk Found
Issue came up where the server didn’t recognize the disk on boot. This was right after I rebooted the server post running the script. I believe this is related to all of the EFI partition labels I had. Couldn’t find the appropriate one. So, the server failed to boot to the OS.
Little more research is required so I can explain this better.
To resolve the issue I needed to delete all of the boot options that were availailable in the UEFI boot menu of the server and choose the disk again. After removing all of the UEFI labels and choosing the appropriate disk once they were deleted, I was able to boot into Oracle. I have checked and this change resolves the issue across reboots.
Closing Notes
Looks like the system has been migrated/converted to Oracle Linux Server 7.9. The whole purpose behind this was to see if the script that is pushed out by Oracle works as expected. Looks like it does. Performed a system upgrade to the server and it looks like everything is working as expected. We have successfully switched over from CentOS 7.9 to Oracle Linux Server 7.9.
The next steps for this server will probably be upgrading it to Oracle Linux Server 8.
