In TIA Portal 18 I get the error that wincc should be verion 7.5. The exact error is: "Migration failed because the project was created with a version prior to WinCC V7.5. Convert the project to WinCC V7.5 and migrate it again." But when I want to migrate to version 7.5, I get following error and project opens without any error or message in WinCC v7.5. "A migration is not necessary. The project is already up-to-date". I tried this with wincc v7.5 (without sp), v7.5+sp1 and v7.5+sp2 and it was the same in all versions. Any idea?

My recommendation, if you already have a V18 license, is that you migrate to WinCC Prof V17 (there is backward compatibility in TIA Portal licensing) and then maybe upgrade the project to V18. Useful information: TIA V17- Migrating WinCC V7 projects
