Migration from CentOS 8 to CentOS 8 Stream

---

It's always a good idea to back up all your files before switching to CentOS 8 Stream, or any other operating system for that matter, so you're not caught off guard if something goes wrong.

For converting CentOS 8 to CentOS 8 Stream use the below commands:

sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-Linux-*

sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-Linux-*

dnf install centos-release-stream

dnf swap centos-{linux,stream}-repos

dnf distro-sync

The script starts by recognizing all of the CentOS Linux 8 to CentOS 8 Stream repositories. It then replaces CentOS 8 Linux packages and repositories with their CentOS 8 Stream counterparts.

After completing the migration process, Continue with the below commands:

Check CentOS version

cat /etc/os-release

Reboot

reboot

That's all there is to it. You can now enjoy the stability and other benefits of CentOS Stream 8 for free, just as you did with CentOS Linux System.

Now you have successfully migrated from CentOS 8 to CentOS 8 Stream.
