General Information

Backup

Before upgrading a project a full backup is recommended!

DemoApplication

When you install a WinCC OA 3.18 patch, the data of the DemoApplication is reset. Back up your data before installing a patch.

Linux

Projects of the versions 3.5 and 3.6 cannot be updated to the Version 3.18 under Linux. Update your project under Windows (see chapter Update or patch project) and then start it under Linux.

Older Versions

In projects older than 3.1, the project must be updated to 3.1 before it can be updated to 3.18.

Redundant Projects

For a description of how to upgrade a redundant project see: WinCC OAUpgrade of a redundant project.

Root User

Note also that the WinCC OA user "root" has to be enabled when updating a project. Otherwise the project cannot be updated.

System Number

For upgrading a WinCC OA project from version 3.1 to 3.18 it is necessary to change the system number to a value below 128. If the system number cannot be changed (e.g. plant project without the possibility for further configuration) additional WinCC OA tools can be used. They can be obtained through the WinCC OA Support.

Secure Project - SSA

Important: Please note that upgrading a project to a current WinCC OA version cannot automatically create a secure standard project from a project of earlier versions. This hardening of your project must be carried out manually. Further information on this can be found in chapter Server-side Authentication for Managers, Server-side Authentication for UI Managers as well as within the Security Guideline.
