|Importing Projects at Startup|
In the next window, press the import multiple projects button. Specify the older version's workspace as the root directory. This screenshot shows the previous versions (4.2.1) workspace as the root directory. The listed projects are to be moved over to the new version (4.2.2).

Projects can also be imported outside of startup by the File > Import menu.
If you design custom component, remember to migrate any settings. From Window > Preferences set the folder for the Talend Component Designer and Talend > Components tabs.
