You can automate a major OS upgrade on a Docker-heavy host by using a staged process that manages Docker services, runs pre-flight checks, handles cleanup, and performs post-upgrade verification via SSH.

A staged OS upgrade process systematically manages Docker stacks and services during the transition, utilizing pre-flight checks, cleanup, and interactive verification to ensure the host and its containers are fully operational.

To perform an automated OS upgrade over SSH, you need SSH access and appropriate system permissions on the target host to manage Docker services and execute pre-flight and post-reboot verification steps.

Interactive verification during an OS version upgrade provides guided steps for critical tasks like bootloader checks and post-reboot verification, ensuring the system is fully operational before completing the process.

Yes, you can use this automated upgrade process to transition a host from one Ubuntu LTS version to another, ensuring all Docker services are properly managed and verified after the upgrade.
