Step 3. Select Organization
At the Organization step of the wizard, use the Restore from drop-down list to select a Salesforce organization whose metadata you want to restore. For a Salesforce organization to be displayed in the list, it must belong to the company specified at step 1.
By default, metadata is restored to the same Salesforce organization. However, you can choose to restore metadata to another organization — to do that, use the Restore to drop-down list. For a Salesforce organization to be displayed in the list of available organizations, it must belong to the company specified at step 1 and be compatible with the organization whose metadata you want to restore. This means that you can restore from a production or sandbox organization only to its sandbox copies.
