Alma Linux Update for Legacy Customers using OVA

CentOS has announced the end of life for their version 6 and 8 operating systems. This means CentOS will no longer provide security patches, vulnerabilities, or bug fixes for these operating systems. As a result, Alert Logic is helping customers update all Alert Logic appliances running on out-of-date operating systems.

Update your appliance to Alma Linux using the documentation below.

As we transition all customers to Alma Linux, Alert Logic will continue to maintain necessary security updates for virtual CentOS versions 6 and 8 for a limited period, to ensure all customers remain secure. This support is valid until the following dates depending on the appliance type:

  • Virtual IDS to January 31, 2023
  • Virtual Log Manager to June 30, 2023


You must be running VMWare ESXi 6.5 or higher before updating the Alert Logic appliance to Alma Linux.

How to update for legacy customers using OVA image

You must install and claim a new appliance, ensure that agents are configured to connect to the new appliance, and then terminate the old appliance.

Ensure the new appliance has the same firewall rules as the old appliance, both inbound and outbound.

  1. You must install a new appliance for every appliance you are currently running with the new OVA image. See Install and Configure the Virtual Appliance

  2. After the new appliance(s) are installed and claimed, add the new appliance to the existing appliance Assignment Policy

  3. After the old appliance is terminated, verify the agent is sending data to the new appliance. To verify in the Alert Logic console:

    1. Click the Configuration tab.
    2. Click All Deployments.
    3. Click Networks and Protected Hosts, and then click the Protected Hosts tab.
    4. Click on the agent to see more details.

    Statistics are updated every 15 minutes in the Alert Logic console.

  4. After the assignment policy has the new appliance, you can terminate the old appliance and remove it from the assignment policy. The agents will automatically shift over to the new appliance(s). To learn how to manage assignment policies, see the Delete an assignment policy section.

  5. After you have confirmed the new appliance is running, the assignment policy has the new appliance and the old appliance is terminated, you can submit a ticket to Alert Logic Technical Support with the ID of the old appliance for them to decommission.
