5.2. Upgrade your Security Center from v1 to v2

In this chapter we will explain how to upgrade your Security Center v1 to the newest version. Since we mainly focus on the new Version 2 of the Security Center in this document, we want to help you through the upgrade process from your older Version 1 of Security Center the newest one, so you can make use of the newest features.

If you are running your Security Center Frontend and Backend on two separate servers, you will have to do the steps below for both servers. You can upgrade them at the same time to reduce downtime.

5.2.1. New Update Servers

We are using a new update server for the new versions of the Security Center. Please make sure the following server is reachable by both your Frontend and Backend server:

Description	Port	Source	Destination
Product Updates	443/tcp	Security Center Frontend & Backend	update-301.nextron-systems.com

Please make sure your local firewall allows the connection to the new update server, otherwise the upgrade will not work.

5.2.2. Preparing for the Upgrade

To prepare for the upgrade, make sure that you have an up to date backup of both your Security Center backend (sometimes referred to as "model") and the frontend. We advise to take a snapshot of the VMs with your hypervisor.

After you created a backup/snapshot, we need to update both frontend and backend servers to the newest version. If you have the frontend and backend installed on the same system, you need to run the next commands only once. If you have two separate servers, repeat the next steps for each of them.

Connect to your Security Center v1 via SSH. Update your current Security Center v1 to the newest version:

nextron@seccenter:~$ sudo apt update && sudo apt dist-upgrade
[...]
Do you want to continue? [Y/n] y

Please confirm the linux upgrade by pressing y and enter. This will not upgrade your Security Center, only the underlying linux operating system.

Hint

This process might take a while.

5.2.3. Performing the Upgrade

After we prepared the system(s) for the update, we can run the following command to install the version 2 of the Security Center. Please note that this step can not be reversed, and your Security Center will be running with the newest version after the update has finished.

nextron@seccenter:~$ start-asgard-update
Created symlink /etc/systemd/system/multi-user.target.wants/asgard-updater.service → /lib/systemd/system/asgard-updater.service.
Successfully started the ASGARD update process.
To monitor the update progress and view log files, you can use the following command:
sudo tail -f /var/log/asgard-updater/update.log

Warning

Your server will restart multiple times during the upgrade process. Do not restart the server manually. You can log into the server and run the following command to monitor the progress:

nextron@seccenter:~$ sudo tail -f /var/log/asgard-updater/update.log

Once your update is finished, you should find the following message in the update log:

nextron@seccenter:~$ sudo tail /var/log/asgard-updater/update.log
[...]

You can now connect to your Security Center's Web UI as usual.
