5.5 How to migrate the WinCC data
Introduction
This chapter describes the migration of WinCC projects of WinCC V6.2 SP3 or higher to WinCC
V7.4.
You have two options of migrating the projects:
● Migration of the configuration data and runtime data when opening an old project
● Using WinCC Migrator to migrate several projects in a single step.
There is no difference between single-user projects, multi-user projects and clients with their
own projects with regard to migration.
WinCC projects before V7.2 are migrated to UNICODE. Tables that do not originate from
WinCC are excluded from migration.
The time it takes to migrate a project depends on the project size and computer performance.
The time it takes to migrate the runtime data varies depending on the number of messages
and tags. The operation may take several hours.
Note
Generate a backup copy of the project prior to migration. You can rely on this copy of the
original project to retrieve your data if migration fails.
If you have used a DDE connection in WinCC prior to V7.0, you must remove this connection
prior to migration. DDE is no longer supported as of WinCC V7.0.
Using WinCC Project Migrator to migrate the WinCC projects
1. Open "Simatic > WinCC > Tools > Project Migrator" in the Start menu of the operating
system. Project Migrator opens with the "CCMigrator - Step 1 of 2" start window.
2. Select the project directory in which the WinCC project is located by clicking the button "...".
If migrating several projects, select the corresponding paths of the directories that contain
the WinCC projects.
3. Set the language of the computer on which you have created the project or projects. The
language version that was set in the OS language options for non-Unicode programs or in
the system locale is set by default.
4. Click "Migrate".
The "CCMigrator - Step 2 of 2" window opens. Project Migrator displays the migration steps.
Wait for successful completion of the migration. The migration of a project may take several
hours.
5. If migration was successfully completed, the Project Migrator sends the following message:
"WinCC project migrated successfully".
6. Click "Finish".
