After loading the Migration Wizard, click on the Start Migration button in the Overview page to begin the migration process. You will first connect to the source PostgreSQL database. Here you will provide the information about the PostgreSQL RDBMS that you are migrating from, the ODBC driver that will be used for the migration, and all of the parameters required for the connection. The name of the ODBC driver is the one you set up when you registered your psqlODBC driver with the driver manager.
Opening the Database System dropdown will reveal each RDBMS that is supported on your system. Select PostgreSQL from the list. Below that is the Stored Connection dropdown, which is optional. Stored connections will be listed here, which are connections saved after defining a connection with the Store connection for future use as checkbox enabled.
The three Connection Method options are:
ODBC (manually entered parameters): Each
parameter, like a username, is defined separately
ODBC Data Source: For pre-configured data
ODBC (direct connection string): A full
ODBC connection string
The psqlODBC driver does not allow a connection without specifying a database name.
