Upgrading WinCC clients
WinCC clients can only be upgraded starting with WinCC V7.2.
To upgrade a WinCC client with a version prior to WinCC V7.2, follow these steps:
1. Perform an upgrade installation to WinCC V7.3.
2. Perform an upgrade installation from WinCC V7.3 to WinCC V7.4.
If you want to upgrade a version prior to V7.2 to V7.4, the SQL Standard Server is installed
instead of SQL Express. This installation displays the license requiring acknowledgment
message on the WinCC client.
Information on migrating projects
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.
You still have to make some project settings after migration.
