# Migrating to this Release

This topic contains information about changes that may affect existing projects when migrating projects from the previous release of Cognex Designer (Cognex Designer 4.2) to the current release of Cognex Designer (4.3).

Note: For more information about migrating from earlier releases, see Release History.

- Handling Components that were created and saved while using Cognex Designer with a different language.

  In case you are using a project that was created and saved with an earlier version of Cognex Designer (3.0 to 4.1) and with a different language setting than what you are using now, then any Components you have configured for the project will not be loaded in Cognex Designer 4.3. Instead, you have to re-add the missing Components manually.
