The Data Transfer Wizard enables you to identify the source and destination for exporting and loading data. The wizard displays the profile name of the database connection to be used to transfer the data. Be sure to verify that you selected the correct profile.

Each data transfer operation requires that you specify the source and destination for the transfer operation. The Source Type and Destination Type fields indicate the type of data transfer operation you selected.
