In order to upgrade and do it compatible with the new driver version, this transaction should be now:
.. code-block:: js
const createTranfer = BigchainDB.Transaction.makeTransferTransaction(
[{ tx: txCreated, output_index: 0 }],
[aliceOutput],

const signedTransfer = BigchainDB.Transaction.signTransaction(createTranfer, keypair.privateKey)
The upgrade allows to create transfer transaction spending outputs that belong to different transactions.
So for instance is now possible to create a transfer transaction spending two outputs from two different create transactions:
.. code-block:: js
const createTranfer = BigchainDB.Transaction.makeTransferTransaction(
[{ tx: txCreated1, output_index: 0 }, { tx: txCreated2, output_index: 0 }],
[aliceOutput],
