Migrating from Ubuntu 20.04 to 22.04: A Comprehensive Guide

Now, lets delve into the process involved with a seamless migration from Ubuntu version 20.04 to the more recent 22.04.

Backup Your Data

Before diving into the migration process, it’s crucial to safeguard your data. Back up your important files, documents, configurations, and any other data you can’t afford to lose. For example, if you current 20.04 version is a virtual machine, you can simply take a snapshot of it. There are also several solutions for backing up physical machines which are beyond the scope of this article. This ensures that even if something goes awry during the migration, your valuable information remains intact.

Check System Requirements

Ensure your system meets the minimum requirements for Ubuntu 22.04. While the requirements are not expected to change dramatically from the previous version, it’s always wise to double-check to avoid compatibility issues.

Update Current Installation

Before initiating the migration, ensure your Ubuntu 20.04 installation is up-to-date. Run the following commands in the terminal and reboot your machine:

					$ sudo apt update
$ sudo apt upgrade
$ sudo apt dist-upgrade

$ sudo /sbin/shutdown -r now

This will ensure that you have all the latest patches and updates installed before proceeding further.

Perform the Upgrade

Ubuntu provides a built-in tool called do-release-upgrade to facilitate the upgrade process. Open a terminal and execute the following command:

					$ sudo do-release-upgrade


The upgrade process will begin and perform all of the necessary preliminary checks required to ensure the upgrade to 22.04 is successful.
