||
## Types of Upgrade
|
||
|
||
There are two methods to upgrade to Ubuntu 22.04 version. The clean upgrade method and inline upgrade method.
|
||
|
||
### Clean Upgrade
|
||
|
||
In this method, you will need to download the Ubuntu 22.04 [ISO](https://www.iso.org/home.html) image from their official download page, then boot your system from the ISO. Following that you need to format your existing installation and then install the newer version of Ubuntu on your system. Advice: this method is not suitable, because you need to backup all your configuration file and reinstall all necessary software on the new system.
|
||
|
||
### Inline Upgrade
|
||
|
||
In this method, you upgrade your existing system without losing any configuration files and reinstalling applications. Perform an [inline upgrade](https://cloudinfrastructureservices.co.uk/ubuntu-vs-linux-whats-the-difference/) via GUI or CLI method. This method downloads and installs all packages and a new releases of the operating system on the same system. Compared to a clean upgrade, this method is the fasted method to perform the upgrade.

|
||
|
||
In this section we navigate you through steps how to upgrade from Ubuntu 20.04 to Ubuntu 22.04.
|
||
|
||
### Prerequisites
|
||
|
||
Before you start with the system upgrade process, please check the following requirements. If anything missing from the below list, you must implement it before the upgrade process.
|
||
|
||
- A root user or a user with sudo privileges is configured on your server with [SSH access](https://cloudinfrastructureservices.co.uk/vpn-vs-ssh-whats-the-difference/).
|
||
|
||
- Minimum 20 GB of free disk space available on your system.
|
||
|
||
- Fast and stable internet connection to perform the upgrade.
|
||
|
||
- Close all running applications.
|
||
|
||
### Backup Your Important Data
|
||
|
||
Before upgrading your system, it is always recommended to backup your files and directory and place them in a safe location. So if your upgrade process failed then you don’t worry about losing your data. If your server is hosted on the [VPS](https://www.ibm.com/in-en/topics/vps) or VM then create a [snapshot](https://snapshot.org/) of your VM to VPS. So that you can restore it easily in the event of a failed upgrade.
|
||
|
||
### Update and Upgrade Existing Packages
|
||
|
||
First, get a list of all packages that needs upgrade using the following command.
|
||
|
||
Next, update the system package cache using the following command.
|
||
|
||
Now, upgrade all the packages to the latest version with the following command.
|
||
|
||
This will take some time to upgrade all the packages to the latest version. After the successful upgrade, restart your system to use the latest kernel that comes with the new upgrade.
|
||
|
||
Next, remove all unwanted packages, dependencies and cache with the following command.
|
||
|
||
Once you are done, please proceed to the next step.
|
||
|
||
### Verify the Existing Server Version

|
||
|
||
### Allow Port 1022 Through UFW
|
||
|
||
By default, [SSH](https://www.ucl.ac.uk/isd/what-ssh-and-how-do-i-use-it) uses port 22. However, during the upgrade process, Ubuntu starts the SSH service on port 1022. Connect to your server via SSH if anything goes wrong.
|
||
|
||
If you are using the [UFW](https://help.ubuntu.com/community/UFW) [firewall](https://cloudinfrastructureservices.co.uk/top-15-best-open-source-firewalls-for-linux-windows/) and upgrading your server via SSH connection then you will also need to allow port 1022 via UFW. Allow port 1022 with the following command.
|
||
|
||
Then, reload the UFW firewall to apply the changes.
|
||
|
||
Once you are done proceed to the next step.
|
||
|
||
