Updating ATA to version 1.9


If ATA is not installed in your environment, download the full version of ATA, which includes version 1.9 and follow the standard installation procedure described in Install ATA.

If you already have ATA version 1.8 deployed, this procedure walks you through the steps necessary to update your deployment.


Only ATA version 1.8 (1.8.6645) and ATA 1.8 update 1 (1.8.6765) can be updated to ATA version 1.9, any earlier version of ATA can't be directly updated to ATA version 1.9.

Follow these steps to update to ATA version 1.9:

  1. Download the update version of ATA 1.9 from the Download Center or the full version from the Eval center.
    In the migration version, the file can be used only for updating from ATA 1.8. In the version from the Eval center, the same installation file (Microsoft ATA Center Setup.exe) is used for installing a new deployment of ATA and for upgrading existing deployments.

  2. Update the ATA Center

  3. Update the ATA Gateways


    Update all the ATA Gateways to make sure ATA functions properly.

Step 1: Update the ATA Center

  1. Back up your database: (optional)

    • If the ATA Center is running as a virtual machine and you want to take a checkpoint, shut down the virtual machine first.

    • If the ATA Center is running on a physical server, see the Disaster recovery article for information about backing up the database.

  2. Run the installation file, Microsoft ATA Center Setup.exe, and follow the instructions on the screen to install the update.

    • On the Welcome page, choose your language and click Next.

    • If you didn't enable automatic updates in version 1.8, you are prompted to set ATA to use Microsoft Update for ATA to remain up-to-date. In the Microsoft Update page, select Use Microsoft Update when I check for updates (recommended). Keep ATA up-to-date image

      This adjusts the Windows settings to enable updates for ATA.

    • The Partial data migration screen lets you know that previously captured network traffic, events, entities and detection related data is deleted. All detections work immediately with the exception of abnormal behavior detection, abnormal group modification, Reconnaissance using Directory Services (SAM-R), and encryption downgrade detections which take up to three weeks to build a complete profile after the required learning time.
