Migrate PBS to Ubuntu 22.04
Updated over a month ago

This article describes the steps to migrate PBS from Ubuntu 18 to Ubuntu 22.

Before we begin

  1. Make sure there are no pending backups to be uploaded to Cloud by running the following command:
    ​zfs list -t snapshot

  2. Internet connectivity should be available on PBS.

  3. Stop any RMAN backup scripts running on the oracle servers while an upgrade is in progress.

  4. Run upgrade when no RMAN backups are scheduled.

  5. Perform the following steps before you migrate PBS:

i. Run the following commands to check system health:

         sudo apt update         sudo apt upgrade         sudo apt dist-upgrade         sudo apt autoremove 

ii. Document installed softwares by running the following command:

dpkg --get-selections | sudo tee installed-software.txt > /dev/null

Copy installed-software.txt to some other local server.


Note:

To upgrade from one LTS version of Ubuntu to another LTS version, you must first upgrade to intermediate LTS versions. For example, if you want to upgrade from Ubuntu 18.04 to Ubuntu 22.04, you must first upgrade from 18.04 to 20.04 and then to 22.04.
