Migration of WinCC projects 2023
YouYube Video Tutorial:-https://youtu.be/0eYSLPmofNU
This section contains information on the migration of WinCC projects created in WinCC V6.2 SP3 or higher.
When you open a project of a previous version in WinCC V7.4, you are prompted to migrate it. However, you may also use WinCC Project Migrator to migrate several WinCC projects in a single step.
Prior to migration, it is recommended to make a backup copy of the original version of the project. For more information on this, refer to the “Working with
WinCC” > “Working with projects” > “Copying and duplicating projects”
section in the WinCC Information System.

Multi-user Projects
When you are working with a multi-user project in WinCC V7.4 that was created in the previous version, migrate the individual multi-user projects from all servers in the system.
Redundant Systems in Normal Operation
A project can be upgraded in a redundant system without deactivating operation. This requires that you update the server, clients with their own project and clients without their own project in a certain sequence. Detailed
instructions are provided in the section “Upgrading Redundant Systems in Normal Operation”.
| Notice |
| Migrating redundant systems without extended interruption In order not to affect system operation, it is essential to observe the sequence of steps described and to complete all the steps without any long interruptions. A client may always only be connected to one server, on which the same WinCC version is installed. |
Behavior during migration of ServiceMode projects
At the start of migration, the Migrator checks whether or not the project on hand is a ServiceMode project. The following is also verified if it is a ServiceMode project:
- If a service user has been entered
- If the service user is available
- If the service user is a member of the “SIMATIC HMI” group
- If the service user is able to log on
An error message is output and the migration process is aborted if one of these criteria is not met.
The central archive server WinCC/CAS is migrated to Process Historian
In WinCC V7.2 and higher, the data of the WinCC/CAS is migrated to SIMATIC Process Historian. Observe the migration description in the Process Historian documentation.
Migration of chip cards when using the “Chip card reader” option With WinCC V7.3 and later, the user information on the smart card is saved with an improved hash function for passwords. After upgrading, you must re-assign the passwords for all WinCC users in all projects, which means server projects and clients projects. This means that you have to write all chip cards in use once again with the corresponding users in the User Administrator. Afterwards, only the new user information specified as of WinCC V7.3 exists in the projects and on the chip cards.
Converting project data
You may also import selected project data and files from projects created in a previous version for use in a new WinCC project. For this purpose, for example, you need to adapt screens and script files to the current version of WinCC and convert these to the current format.
| Note It is not possible to convert an individual picture or a library object. Conversion of pictures and libraries may take some time. |
| Notice |
| Conversion is irrevocable Conversion of data cannot be undone. Conversion starts immediately once you have selected the entry. No confirmation prompt is displayed. |
Procedure
- Select the “Tools > Convert project data” menu command in WinCC
Explorer. - Select the project data to be converted:
- Pictures and faceplates
- Global libraries
- Project libraries
- Page layouts and line layouts
- C and VB project functions and actions
- C and VB standard functions
- Data for Basic Process Control
- Confirm with “OK”.The selected data is converted to the current version of WinCC.
WinCC projects that were created with versions prior to WinCC V7.0
Migrated WinCC projects with SQL Server 2000 databases
WinCC projects that were created with versions prior to WinCC V6.2 SP2 include database settings of the SQL Server 2000.
To access these databases with WinCC V7.4 and higher, you must adapt the compatibility settings.
For additional information, refer to “How to migrate SQL Server 2000 databases“.
| Note No migration of a WinCC V6.2 SP3 project if a WinCC editor has never been opened before If you have never opened an editor, for example, Alarm Logging or Text Library, in a WinCC V6.2 SP3 project, you cannot migrate the project to WinCC V7.4. |
