Unsupported upgrade paths

    for Windows XP Embedded 5.1

    for Mac client earlier than 12.1.4. Or you can upgrade it to 12.1.4 or later.

Additional information

  • Any Symantec Endpoint Protection client migration for version earlier than 12.1.x is not supported.
  • You cannot upgrade Symantec Endpoint Protection Manager 11.0.x or Symantec Endpoint Protection Manager Small Business Edition 12.0.x directly to any version of Symantec Endpoint Protection Manager 14. You must first uninstall these versions or perform an upgrade to 12.1.x before an upgrade to the latest release of 14.x.
  • You cannot upgrade
    Symantec Endpoint Protection Manager
    12.1.6 MP7 to version 14 because the database schema version in 12.1.6 MP7 is later than in 14. Instead, you must upgrade 12.1.6 MP7 to 14 MP1 or later.
  • 14.0.x dropped support for Windows XP, Server 2003, and any Windows Embedded operating system that is based on Windows XP. Symantec Endpoint Protection Manager 14.2 RU1 can manage these computers as legacy 12.1.x clients, although 12.1.x clients are EOL. For these clients, you may want to use a Symantec product that still supports these legacy operating systems, such as Data Center Security (DCS).
