Migrate's Execute Batch command lets you run a migration without opening the MIG file in the Migrate window. To run a MIG file in this way, select Execute Batch from the File menu. In the Select Batch File dialog box, select the MIG file you want to run. When you click OK, the migration is immediately executed.
The Execute Batch command does not affect the current migration settings (e.g., selected tables and options). Specifications in effect before Execute Batch is invoked will be in effect when execution of the MIG file is complete.
