Upgrade
CylanceON-PREM

Administrators can apply the latest
CylanceON-PREM
upgrade package to the virtual appliance. The upgrade path for
CylanceON-PREM
is sequential. For example, if you have version 1.4.3 installed, you must upgrade to 1.4.5, then 1.5.4.1, then 1.6, and so on until you upgrade to the latest release.
It is recommended to enable maintenance mode and take a snapshot of the virtual appliance before upgrading. When you update the
CylanceON-PREM
virtual appliance, there is no way to change from an internal database to and external database, or vice versa.
  1. Obtain the latest
    CylanceON-PREM
    file.
  2. In the console, on the menu bar, click
    Configuration > Settings
    .
  3. Click
    Maintenance Mode
    . This pauses site activity, including communication between the virtual appliance and the Agents, to ensure you can take a complete VM snapshot.
  4. Take a snapshot of the
    CylanceON-PREM
    virtual appliance.
  5. Under
    CylanceON-PREM
    Info, click
    Upgrade
    .
  6. Select the
    I have taken a VM snapshot
    check box. Click
    Proceed with Upgrading
    .
  7. Click
    Browse for a file
    , select the
    CylanceON-PREM
    file you want to use for this update. Click
    Open
    . Optionally, you can drag and drop the file to select it.
  8. Click
    Start Upgrade
    . During the upgrade, there are two things to look for: the
    Update is in progress
    message and a
    Successful update
    notification. After the Update Success modal displays, the virtual appliance will restart. While restarting, the
    CylanceON-PREM
    Console will be unavailable. If the entire upgrade process, including the restart, takes longer than 10 minutes, you must re-log in to the
    CylanceON-PREM
    Console.
  9. After the upgrade is complete, click
    Maintenance Mode
    and disable it. Site activity resumes.
    If you refresh the Settings page after the upgrade completes and the web browser displays a blank page, clear the browsing data.
