This section reviews a simple migration script and assumes some familiarity with the GRT shell. If you haven't yet done so, read Chapter 10, The Generic Runtime Environment (GRT) Shell.

As noted earlier in Section 9.17, “The Summary Screen”, if you choose, you can generate a migration script when migrating a database. Doing this creates a Lua script of the entire migration process. You can find out more about Lua by going to lua.org. However, if you have some familiarity with programming you should be able to make sense of this script without too much effort.

For a better understanding of the migration script, it is useful to have the GRT shell open within the MySQL Migration Toolkit. In this way you can examine the various objects created during migration by clicking on them in the Globals Tree panel. To save the application state and have access to these objects, migrate a database as described in Chapter 9, The Migration Process In-Depth, and when you reach the Summary step, choose the menu options File, Store current application state .... This will save an XML file of the entire migration process. You can now reload the migration state whenever you wish.
