🐧 migrate-to-oracle-linux

This repository contains two scripts for Oracle Linux migration workflows:

• 🔄 migrate-to-oracle-linux.sh migrates supported Enterprise Linux systems to Oracle Linux, including the Amazon Linux 2 to Oracle Linux 7 exception.
• 🪞 mirror-oracle-linux-yum.sh builds an Oracle Linux yum mirror that migration targets can use instead of reaching yum.oracle.com directly.

📍 Where To Run Each Script

🪞 Run mirror-oracle-linux-yum.sh only on the yum mirror system.

🎯 Run migrate-to-oracle-linux.sh on each system that will be migrated to Oracle Linux.

These are separate roles. The mirror script prepares and serves Oracle Linux repositories. The migration script changes the operating system installed on a target host.

• 🪞 Yum mirror script README

🚀 Typical Workflow

1. 🪞 On the yum mirror system, build and publish the Oracle Linux mirror:

   sudo ./mirror-oracle-linux-yum.sh \
     --dest /srv/mirror \
     --public-base-url https://yum-mirror.example.com \
     --jobs 4

2. 📝 Note the --yum-mirror value reported by the mirror script.

3. 🎯 On each system being migrated, run the migration script:

   sudo ./migrate-to-oracle-linux.sh -y --yum-mirror https://yum-mirror.example.com

The mirror script writes the migration mirror value to:

<dest>/migrate-to-oracle-linux-yum-mirror.txt

🌐 Direct Internet Workflow

If migration targets can reach yum.oracle.com directly, the mirror is optional:

sudo ./migrate-to-oracle-linux.sh -y

For proxied internet access, run the migration script on the target system with --proxy:

sudo ./migrate-to-oracle-linux.sh -y --proxy http://myproxy.example.com:3128

--proxy cannot be used with --yum-mirror.
