Hello,

Try converter from http://convertdb.com/oracle/mssql

Check the option "overwrite existing database" in database options at customization step.

Use "bulk insert" option as well to increase the speed.

Make sure "automatic structure update in the session" option is checked at execution stage.

Probably you should create several sessions for each scheme you need to migrate.

You can start several scheduled jobs simultaneously from command line or in GUI mode.

regards,

Dmitry
