Issue



You have a previous version of Scan Engine and seek to upgrade to Scan Engine 5.2. You want to know how to do this without losing your current configuration settings.


Solution




In each upgrade scenario, Symantec recommends backing up your existing settings before proceeding and testing your upgrade path in a test environment before implementing in production.


To upgrade from Scan Engine 5.1.x to Scan Engine 5.2.x on Windows
  1. Install Scan Engine from the installation material
  2. When Scan Engine 5.2 detects the previous install, it will prompt you to either Install or Upgrade. To retain your existing configuration, click Upgrade, then click Next.


To upgrade from Symantec Antivirus Scan Engine 4.3.x to Scan Engine 5.2.x on Windows
As above. Note that Scan Engine 5.2 will not gracefully update all SAVSE4.3 settings. See 'About migrating from version 4.3.x' in Technical Information, below, for more information.


To upgrade from Symantec Antivirus Scan Engine 4.0.x or earlier to Scan Engine 5.2.x
Upgrades from these earlier versions are not supported. Symantec recommends the following:
  1. Record your settings by collecting screenshots within the Symantec Antivirus Scan Engine 4.0.x User Interface
  2. Uninstall the existing Symantec Antivirus Scan Engine 4.0.x
  3. Install Scan Engine 5.2.x
  4. Configure for your environment.
  5. Test to identify any possible obstacles.

Technical Information

About migrating from version 4.3x
If you are migrating from version 4.3x, consider the following items:

  • The ArchiveTypes setting from version 4.3 is not preserved. Instead, the DecEngines setting in version 5.2 uses a default value.
  • Exclusion lists are not upgraded. For security reasons, changes were made to the default exclusion list.
  • Version 5.2 does not support inclusion lists.
  • Domain blocking settings are not preserved, and the syntax of the entries has changed. The previous settings are saved into an upgrade folder in the installation directory for review and re-entry by the user in the new format.
  • If "Enable trickle" is selected, then "Blocking by File Name" and "Blocking by File Size" are disabled after the upgrade.
  • If the LiveUpdate interval in Symantec Scan Engine 4.3 is set to a value that is not supported in Symantec Scan Engine 5.2, then the interval is reset to every 2 hours.
  • Upgrades on Linux and Solaris run under the configured user of the previous installation. To change the user that Symantec Scan Engine runs as, uninstall the existing installation, and perform a clean installation of version 5.2. The installation user interface asks what (non-root) user you want Symantec ScanEngine to run as.
  • Symantec Scan Engine tries to use port 8005 after an upgrade for the Secure Socket Layer (SSL). If that port is in use, manually change the SSL port to an available port number. Then restart the Symantec Scan Engine.
  • If you upgrade from version 4.3.7 or later, the maximum file size settings are not preserved. The maximum file size threshold is automatically set to 2,147,483,648 bytes (2 GB).
  • Additional information regarding the settings conversions are in the Implementation Guide for Scan Engine 5.2
  • During the upgrade, the service account that the Symantec Scan Engine service will default to the local System Account. If, prior to the upgrade, the service account was running under a specific user, you will need to change the service account user log on to that user account again.
