Step 1: Do note down and list enabled repos:
yum repolist
yum repolist enabled > /tmp/pre.update.dnf.repo.txtStep 2: Run update
sudo dnf updateStep 3: Installing CentOS Stream packages
sudo dnf in centos-release-stream -yStep 4: Migrating From CentOS 8 to CentOS Stream
sudo dnf swap centos-linux-repos centos-stream-repos -yStep 5: Upgrading CentOS 8 to CentOS Stream
sudo dnf distro-syncsudo systemctl rebootcat /etc/centos-releaseMake sure there are no errors
sudo tail -f /var/log/messages
sudo grep -i -E 'err|wan|cri' /var/log/messages
sudo grep -i -E 'err|wan|cri' /var/log/nginx/error.logA note about 3rd party dnf repos
Some dnf repos may be renamed or disabled to prevent upgrade issues. It would be best if you validated those manually.
yum repolist enabled > /tmp/post.update.dnf.repo.txtdiff /tmp/pre.update.dnf.repo.txt /tmp/post.update.dnf.repo.txt
