Is SmartPLS 4 compatible with SmartPLS 3?

SmartPLS 4 is upward compatible. This means that you can continue to use your data and projects from SmartPLS 3 in SmartPLS 4.

However, projects that have been modified in SmartPLS 4 cannot be used again in SmartPLS 3. Therefore, we recommend that you start SmartPLS 4 with an empty workspace and import your old projects so that you are working on a copy.
