Debian & Ubuntu Upgrade

At Contabo, we always offer you the latest version of many popular Linux operating systems. This tutorial shows you how to upgrade from an old version to the latest Debian (stable) or Ubuntu LTS.

Important:
Before proceeding make sure to have a local backup of all important files, the upgrade might fail and your server becomes inoperable!
In case you are upgrading a VPS with 100% SSD, creating a prior snapshot will be sufficient for backup.
The upgrade really depends on the customization performed on the system and the amount of software installed. The higher the amount of additional software, the higher the risk of package-conflicts which need to be solved manually.

1. Preparation

The system needs to get all pending updates for your software packages, prior to proceeding. If you have not installed updates recently this might take some time.
Packages which were installed due to dependencies and are not needed anymore should be deleted as well.

:~#apt-get update && apt-get upgrade -y
:~#apt-get autoremove

2. Adjusting the apt.conf (Debian)

The following commands will replace "stretch" with "buster" in any repository entry.
In case you manually added additional repositories they might fail, you will have to manually investigate or disable those package sources.

:~#sed -i 's/stretch/buster/g' /etc/apt/sources.list
:~#sed -i 's/stretch/buster/g' /etc/apt/sources.list.d/*

Usually there should be no additional package sources configured and your sources list will have the following configuration:

:~# cat /etc/apt/sources.list
deb http://asi-fs-n.contabo.net/debian buster main non-free contrib
deb http://security.debian.org/debian-security buster/updates main contrib non-free
deb-src http://security.debian.org/debian-security buster/updates main contrib non-free
deb http://asi-fs-n.contabo.net/debian buster-updates main contrib non-free

3. a) Start upgrade (Debian)

The following commands will start the upgrade and will also update the packages.

:~#apt clean && apt update
:~# apt upgrade -y
:~# apt dist-upgrade -y
:~# apt autoremove
:~# cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 10 (buster)"
NAME="Debian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

3. b) Start upgrade (Ubuntu)

Ubuntu has got a Tool/command for this purpose: "do-release-upgrade" it will update to next available LTS version, so 14.04 LTS to 16.04 or 16.04 LTS to 18.04 LTS.
In case the command was not found and the tool is missing, it can be installed with following command:

:~# apt-get install update-manager-core

4. Restart server

In order to use the recently installed kernel, you will have to reboot your server. After rebooting you are running the latest version of Debian (stable)/ Ubuntu LTS.

In case of any issues or inquiries, our customer support team is available to assist you.

Migration using Plesk

The migration of a website is always a challenging task for the webmaster. Beside a loss of reputation and ranking on search engines, dead links or famous 404-errors, there are some other risks during such a migration. But often it is more dangerous to leave the website on an old server, since old software can become a serious security risk.

Plesk Migrator

If you want to migrate from a current Plesk server with an outdated operation system or an EOL Plesk version, cPanel, Confixx, Helm or DirectAdmin server, Plesk provides the Plesk Migrator.

The Plesk Migrator is an extension which needs to be installed first. Within Plesk navigate to "Extensions", search for "Plesk Migrator" and then you can install it.

After the installation you can open the "Plesk Migrator" at the tab "My Extensions".

The next step is to "Start new Migration" and select the panel type, from which you want to transfer the data. Important: For this you need root access via SSH to the source server. Beside password authentication you can add an SSH key to the server.

If SSH access is not available and only FTP is possible, please see the next chapter Site Importer.

After you have entered the login data, the connection to the source server is started and depending on the server, different migration options are shown.

On a Plesk-to-Plesk migration you can see the subscriptions, customers, reseller and hosting plans.

In addition you can either migrate the customers of a reseller or assign them to a new reseller. After everything is selected, you can continue with a click on "Migrate". At first there are some checks on Apache modules or PHP versions. If there are no errors or you want to ignore possible hints, the migration will start and you can watch the status of the migration.

In case you want to restart the migration after some days, you can click on "Restart Migration".

You can find further information in the Plesk Migration Guide and also in a support article.

Site Importer

In many cases, you already have a running website and want to migrate it with a few clicks. Likely examples are: you have just started with Plesk, you manage your website using a different panel like cPanel or DirectAdmin, or you have a server with a pure LAMP installation.

In this case, Plesk offers an extension called Site Import.

This is also an extension which needs to be installed. Therefore navigate to "Extension" in your Plesk and search for "Site Import", which can be installed then.

There a two different ways to import your website with the Site Importer:

You can login as server administrator and open "Site Importer" at "Extension" - "My Extensions". Alternatively you can navigate to the subscription and select "Website Importing". In the next step, you need to enter the login data for SSH or FTP.

After you entered the login data and clicked "OK", the connection to the source server will be started and the necessary information will be gathered.

If the file structure can not be detected automatically, you can enter additional information like the location of the home directory.

Website software like WordPress, Joomla, Drupal und PrestaShop are recognised automatically and the import is easy. Further information can be found in the Plesk documentation.

Beside websites, this useful extension can also import email accounts. For this choose "Mail Importing" in the subscription. After a click on "Import mail messages", you need to enter the login data and destination email account. If the the email server can not be detected through the login data, you can enter the necessary details at "Show advanced options". With a click on "OK" the import starts.

Additional information is also available on the Plesk website.

Conclusion

We cannot eliminate the risks of a website migration, but minimize them since Plesk offers some useful tools to make a migration easier and reduce the human factor. But the most important thing for a successful migration is a detailed and well thought out planning.

Order a VPS from Contabo and you get the Plesk edition of your choice one month for free! You can also find further information on our Plesk information site.

VPS:

Our VPS provide a low-cost entry into the world of servers. The VPS are based on KVM and are set up on host systems with up-to-date and reliable hardware.

With the help of those administration panels, websites, e-mails and much more can be managed easily and quickly.

Each customer also receives root access or administrator rights on his VPS and can therefore install any desired software. This enables a variety of possible applications.

Dedicated servers are ideal for larger projects that require a lot of computing power. They can be easily adapted to individual requirements and needs and are particularly suitable for software development, database applications or virtualization. Dedicated servers can also be connected to an internal network that enables fast local data exchange between several servers.

Likewise, as above for the VPS, you can choose from a variety of current Linux and Windows operating systems with compatible administration panels. In addition, some virtualization operating systems such as Proxmox and XenServer can also be installed, which are ideal for creating and managing your own virtual machines.

Dedicated servers are also suitable for hosting game servers or VoIP applications, as the performance of the server is dedicated.

We currently offer six different dedicated servers that cover the complete performance range.
