What is the difference between an upgrade and an update?

  • Associated product(s)

Configuration Notes:
An upgrade is an upgrade to a new version usually with additional functions. In this case one speaks of a new "major release". This upgrade package is usually billable and also includes a new license. An upgrade is from WinCC V5 to V6, for example.

An update is a further development within a program version (e.g. from WinCC V6.0 SP3 to SP4). Updates are always free of charge and provide no or only minor additional functions.

In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens’ products and solutions constitute one element of such a concept. For more information about industrial security, please visit
