I'm migrating the database from sqlserver to oracle using the tool 'Oracle Migration Workbench'.
First i've create oracle model from the selected database of the sqlserver.
The problem is i have to update the selected tables and procedures in the oracle database. For that what i'm doing is big process, ie Deleting the existing database and migrating from sqlserver to oracle again.
I feel its tedious process. Oracle Migration Workbench has an option to migrate only the selected tables but it is disable, i don't knoe how to make it enable.

Plz give me some suggetion.
Thks for advance.
