Before you begin an upgrade

1. Check that you're upgrading from a supported version. You can upgrade to Deep Security from:

   • Deep Security 11 LTS (GA version or LTS updates)
   • Deep Security 11 Feature Releases
   • Deep Security 12 LTS (GA version or LTS updates)
   • Deep Security 12 Feature Releases
2. Back up the agent computers that you plan to upgrade. Make a system restore point or VM snapshot of each agent.
3. Import the new agent package into the manager. See Import agent software.
4. Upgrade all Deep Security Relays. See Upgrade the Deep Security Relay.

   WARNING You must upgrade all relays before you begin upgrading agents, otherwise, upgrades may fail.

   Note When you upgrade the Deep Security Agent, Deep Security verifies your signature on Deep Security Agent to ensure that the software files have not changed since the time of signing. For more information, see Agent package integrity check.

Solaris agent upgrade notes

• On Solaris 11, if you are upgrading from Deep Security Agent 9.0, you must first upgrade to Deep Security Agent 9.0.0-5616 or a later 9.0 agent, and from there, upgrade to Deep Security Agent 11.0. If you upgrade from an earlier build, the agent may fail to start. If this problem occurs, see Fix the upgrade issue on Solaris 11.
• An upgrade on Solaris may take five minutes or longer to complete in some cases.

AIX agent upgrade notes

Upgrade the agent starting from an alert

1. In the alert, click Show Details and then click View all out-of-date computers. Computers appears, displaying all computers where Software Update Status is Out-of-Date. What is considered 'out-of-date' is determined by version control rules you've set up. For details, see Configure agent version control.
2. Continue with Upgrade an agent from the Computers page or Upgrade the agent by running the installer manually.

Upgrade multiple agents at once

1. In Deep Security Manager, go to Administration > Updates > Software.
2. In the main pane, look under the Computers section to see whether any computers or virtual appliances are running agents for which upgrades are available. The check is only performed against software that has been imported into Deep Security, not against software available from the Download Center.
3. Click Upgrade Agent / Appliance Software to upgrade all out-of-date computers. What is considered 'out-of-date' is determined by version control rules you've set up. For details, see Configure agent version control.

Upgrade the agent from the Computers page

1. In Deep Security Manager, go to Computers, and then:

   • Right-click the computer(s) that you want to upgrade, and select Actions > Upgrade Agent Software.
     Or
   • Select the computer(s) that you want to upgrade, click the Actions button near the top and select Upgrade Agent Software.
     Or
   • Double-click a computer that you want to upgrade and on the Computer details dialog box, click the Upgrade Agent button.

   WARNING You must upgrade your relays before your agents to prevent failures. Learn more. To identify a relay, look for the relay icon ().

2. In the dialog box that appears, select the Agent Version. We recommend that you select the default Use the latest version for platform (X.Y.Z.NNNN). Click Next.

Upgrade the agent on activation

Upgrade the agent from a scheduled task

Upgrade the agent manually

• There are connectivity restrictions between the manager and agent computers.
• Your agent software is too old, and the manager doesn't support upgrading it anymore.
• You prefer to deploy upgrades using a third-party system.

Upgrade the agent on Windows

1. Disable agent self-protection to allow the installer to make modifications to the agent. To disable self-protection:

   1. In the Deep Security Manager, go to Computer editor > Settings > General.
   2. In Agent Self Protection, deselect Prevent local end-users from uninstalling, stopping, or otherwise modifying the Agent or enter a password for a local override.
2. Export the new agent ZIP from the manager. See Export the agent installer for instructions. If multiple new agents are available for your platform, choose the latest one.
3. Copy the ZIP to the agent computer and extract it.
4. Double-click the MSI file in the root of the ZIP file. The installer detects the previous agent and performs the upgrade.

Upgrade the agent on Linux

1. Disable agent self-protection to allow the installer to make modifications to the agent.
2. Export the new agent ZIP file from the manager. See Export the agent installer for instructions. If multiple new agents are available for your platform, select the latest one.
3. Copy the ZIP file to the agent computer and extract it.
4. If the computer uses the RPM package manager (Red Hat, CentOS, Amazon Linux, Cloud Linux, SUSE), run the following command:
   rpm -U <new agent installer rpm>
   The -U argument instructs the installer to perform an upgrade.
   If the computer uses the dpkg package manager (Debian or Ubuntu), enter the command:
   dpkg -i <new agent installer dpkg>

Upgrade the agent on Solaris

1. Export the new agent ZIP from the manager. See Export the agent installer for instructions. If multiple new agents are available for your platform, choose the latest one.
2. Copy the ZIP to the agent computer and extract it.
3. Run the installer:

• Solaris 11, one zone (run in the global zone):
  x86: pkg update -g file:///mnt/Agent-Solaris_5.11-9.x.x-xxxx.x86_64/Agent-Core-Solaris_5.11-9.x.x-xxxx.x86_64.p5p pkg:/security/ds-agent
  SPARC: pkg update -g file:///mnt/Agent-Solaris_5.11-9.x.x-xxxx.x86_64/Agent-Solaris_5.11-9.x.x-xxxx.sparc.p5p pkg:/security/ds-agent
• Solaris 11, multiple zones (run in the global zone):
  mkdir <path>
  pkgrepo create <path>
  pkgrecv -s file://<dsa core p5p file location> -d <path> '*'
  pkg set-publisher -g <path> trendmicro
  pkg update pkg://trendmicro/security/ds-agent
  pkg unset-publisher trendmicro
  rm -rf <path>
• Solaris 10: Create an installation configuration file named ds_adm.file with the following content, and then save it in the root directory. Next, run this command to install the package:
  pkgadd -G -v -a /root/ds_adm.file -d Agent-Core-Solaris_5.10_U7-10.0.0-1783.x86_64.pkg

Content of ds_adm.file

Upgrade the agent on AIX

1. Export the new agent ZIP from the manager. See Export the agent installer for instructions. If multiple new agents are available for your platform, choose the latest one.
2. Copy the ZIP to the agent computer and extract it. A BFF file becomes available.
3. Copy the BFF file to a temporary folder such as /tmp on the AIX computer. For detailed instructions, see Install the agent manually.
4. Upgrade the agent. Use these commands:
   /tmp> rm -f ./.toc
   /tmp> installp -a -d /tmp/<agent_BFF_file_name> ds_agent
   where <agent_BFF_file_name> is replaced with the name of the BFF installer file you extracted.

Upgrade best practices for agents

• Upgrade when the computers are less busy.
• Test the upgrade procedure first in a staging environment before upgrading production servers.
• When upgrading production servers, upgrade one server at a time for the first few servers. Allow a soak period in between each server upgrade.
• After individually upgrading a number of production servers for a given OS version (and application role, on Solaris or AIX), upgrade the remaining servers in groups.
• Also review the Best practices for upgrades.
