Downgrade the Agent from v6 to v5

This guide assumes you upgraded to the Agent v6 using the upgrade guide. If so, choose your OS to see the detailed instructions on how to downgrade your Agent from version 6 to version 5:

Debian Flavored Systems:

  1. Set up apt so it can download through https and install curl and gnupg

    sudo apt-get update
    sudo apt-get install apt-transport-https curl gnupg
    
  2. Remove Beta Repo and Ensure the stable repo is present:

    sudo rm /etc/apt/sources.list.d/datadog-beta.list
    [ ! -f /etc/apt/sources.list.d/datadog.list ] &&  echo 'deb [signed-by=/usr/share/keyrings/datadog-archive-keyring.gpg] https://apt.datadoghq.com/ stable main' | sudo tee /etc/apt/sources.list.d/datadog.list
    sudo touch /usr/share/keyrings/datadog-archive-keyring.gpg
    
    curl https://keys.datadoghq.com/DATADOG_APT_KEY_CURRENT.public | sudo gpg --no-default-keyring --keyring /usr/share/keyrings/datadog-archive-keyring.gpg --import --batch
    curl https://keys.datadoghq.com/DATADOG_APT_KEY_06462314.public | sudo gpg --no-default-keyring --keyring /usr/share/keyrings/datadog-archive-keyring.gpg --import --batch
    curl https://keys.datadoghq.com/DATADOG_APT_KEY_C0962C7D.public | sudo gpg --no-default-keyring --keyring /usr/share/keyrings/datadog-archive-keyring.gpg --import --batch
    curl https://keys.datadoghq.com/DATADOG_APT_KEY_F14F620E.public | sudo gpg --no-default-keyring --keyring /usr/share/keyrings/datadog-archive-keyring.gpg --import --batch
    curl https://keys.datadoghq.com/DATADOG_APT_KEY_382E94DE.public | sudo gpg --no-default-keyring --keyring /usr/share/keyrings/datadog-archive-keyring.gpg --import --batch
    
  3. If running Ubuntu 14 or earlier or Debian 8 or earlier, copy the keyring to /etc/apt/trusted.gpg.d:

    sudo cp /usr/share/keyrings/datadog-archive-keyring.gpg /etc/apt/trusted.gpg.d
    
  4. Update apt and downgrade the Agent:

    sudo apt-get update
    sudo apt-get remove datadog-agent
    sudo apt-get install datadog-agent
    
  5. Back-sync configurations and AutoDiscovery templates (optional)

    If you made any changes to your configurations or templates, you might want to sync these back for Agent v5.

    Note: If you made any changes to your configurations to support Agent v6 only options, these do not work with Agent v5.

  6. Back-sync custom checks (optional):

    If you made any changes or added any new custom checks while testing Agent 6 you might want to enable them back on Agent 5. Note: You only need to copy back checks you changed.

    sudo -u dd-agent -- cp /etc/datadog-agent/checks.d/<CHECK>.py /etc/dd-agent/checks.d/
    
  7. Restart the Agent:

    sudo systemctl restart datadog-agent # Systemd
    sudo /etc/init.d/datadog-agent restart # Upstart
    
  8. Clean out /etc/datadog-agent (optional):

    sudo -u dd-agent -- rm -rf /etc/datadog-agent/
    

Red Hat Flavored Systems:

  1. Remove the Beta Yum repo from your system:

    rm /etc/yum.repos.d/datadog-beta.repo
    [ ! -f /etc/yum.repos.d/datadog.repo ] && echo -e '[datadog]\nname = Datadog, Inc.\nbaseurl = https://yum.datadoghq.com/rpm/x86_64/   \nenabled=1\ngpgcheck=1\nrepo_gpgcheck=1\npriority=1\ngpgkey=https://keys.datadoghq.com/DATADOG_RPM_KEY_CURRENT.public\n       https://keys.datadoghq.com/DATADOG_RPM_KEY_4F09D16B.public\n       https://keys.datadoghq.com/DATADOG_RPM_KEY_B01082D3.public\n       https://keys.datadoghq.com/DATADOG_RPM_KEY_FD4BF915.public\n       https://keys.datadoghq.com/DATADOG_RPM_KEY_E09422B3.public' | sudo tee /etc/yum.repos.d/datadog.repo
    

    Note: due to a bug in dnf, use repo_gpgcheck=0 instead of repo_gpgcheck=1 on RHEL/CentOS 8.1.

  2. Update your local yum cache and downgrade the Agent

    sudo yum clean expire-cache metadata
    sudo yum check-update
    sudo yum remove datadog-agent
    sudo yum install datadog-agent
