Truc Migrer de CentOS 7 vers Rocky Linux 8

Ce truc marche pour migrer vers Rocky Linux depuis CentOS Stream, CentOS, AlmaLinux, RHEL ou Oracle Linux.

D'abord, mettez CentOS 7 à jour; avec un nouveau dépôt car les dépôts officiels de CentOS 7 sont désactivés :

sudo curl -o /etc/yum.repos.d/CentOS-Base.repo https://el7.repo.almalinux.org/centos/CentOS-Base.repo
sudo yum upgrade -y

Ensuite téléchargez les scripts de migration de Rocky Linux :

sudo yum install -y leapp-upgrade leapp-data-rocky

On va ensuite lancer le script de pré-migration :

sudo leapp preupgrade

Ce script va prendre du temps pour arriver à terme. Un rapport en anglais va indiquer les principaux problèmes ou risques et commencer les réparer dans /var/log/leapp/leapp-report.txt et globalement dans /var/log/leapp/ se trouvent tous les informations du rapport.

Lancez le script de migration. Ce script va s'occuper de tout :

sudo rmmod pata_acpi

2. Mettre à jour /etc/ssh/sshd_config pour autoriser le login en root :

echo PermitRootLogin yes | sudo tee -a /etc/ssh/sshd_config

3. Déactiver le module pam_pkcs11 de la configuration PAM pour que la mise à jour ne s'interrompe pas

sudo leapp answer --section remove_pam_pkcs11_module_check.confirm=True

Relancer le script

sudo leapp preupgrade

Quand vous voyez un message « Complete! » à la fin, vous avez juste à redémarrer le serveur.

   Hint: If there was a problem reaching remote content (see stderr output) and proxy is configured in the YUM/DNF configuration file, the proxy configuration is likely causing this error. Make sure the proxy is properly configured in /etc/dnf/dnf.conf. It's also possible the proxy settings in the DNF configuration file are incompatible with the target system. A compatible configuration can be placed in /etc/leapp/files/dnf.conf which, if present, it will be used during some parts of the upgrade instead of original /etc/dnf/dnf.conf. In such case the configuration will also be applied to the target system. Note that /etc/dnf/dnf.conf needs to be still configured correctly for your current system to pass the early phases of the upgrade process.
