Upgrade from opsi 4.2 to 4.3

On supported operating systems, you can upgrade an existing opsi 4.2 installation to opsi 4.3.

Directly upgrading from opsi 4.1 to opsi 4.3 is not supported. You must first upgrade to opsi 4.2 before proceeding to opsi 4.3.

If you are managing your opsi servers using opsi itself, you can do the upgrade using the localboot product l-opsi-server-migrate.

Creating a Backup

Be sure to create a backup before upgrading:

opsi-backup create

From opsi 4.3 onwards, the opsiconfd service is responsible for backup and restore operations (opsiconfd backup/opsiconfd restore). For more detailed information, refer to the chapter Backup of the opsi Server.

Adding new Repositories

First, add the opsi 4.3 repositories to your operating system’s configuration files and include the GPG key of the repository. Remember, you’ll need root privileges for this process.

For Debian, Ubuntu, or Univention Corporate Server (UCS) systems, ensure the directory /usr/local/share/keyrings is present:

sudo mkdir -p /usr/local/share/keyrings

Here are the commands for the supported operating systems:

Upgrading the OS Packages

Once you’ve added the new package sources, you’re ready to begin the upgrade process. Remember, you will need root privileges for this as well.

For RPM-based distributions, be aware that existing configuration files will be replaced with new ones during the upgrade. Make sure to consult the specific instructions for your distribution to handle this properly.

Debian and Ubuntu

apt update
apt dist-upgrade

RHEL, AlmaLinux, and Rocky Linux

yum makecache
yum upgrade

SLES and openSUSE Leap

Single-Server-Setup:

zypper refresh
zypper update

Univention Corporate Server (UCS)

eval "$(ucr shell version/version)"
univention-upgrade  --updateto=$version_version-99

During the process, the system will prompt you to confirm whether you want to update to the next UCS (Univention Corporate Server) version. Please proceed with this update only if you intend to upgrade to the newer version.

Adjusting the Configuration

These two adjustments are optional but recommended:

Set opsiclientd.config_service.permanent_connection = true to enable client and server communication via the opsi message bus.
Set opsiclientd.global.verify_server_cert = true to ensure that the opsi clients verify the SSL server certificates of the servers.

Updating the opsi Packages

The final step involves updating to the latest opsi packages.

If the default settings in /etc/opsi/package-updater.repos.d/ have not been altered, you can upgrade the opsi packages using the following command:

opsi-package-updater -v update

Your opsi 4.2 server has now been successfully updated to version 4.3 and is ready for use.
