If you need to close the MySQL Migration Toolkit part way through the migration process, you can save the state of the MySQL Migration Toolkit to disk and continue later.
To save the current state of the MySQL Migration Toolkit, choose the Store current application state option of the File menu.
To later retrieve the application state and resume configuring the migration, choose the Reload stored application state option of the File menu.
Saving the application state will prove useful when examining scripted migration in Chapter 11, Scripted Migration.
