Unfortunately, optical transceiver modules do not auto negotiate for speed.  Therefore, you cannot connect a 10Gbps interface to a 1Gbps interface.  You need to upgrade both ends before the circuit can be completed.

If you need equipment to support the intermediate step in the upgrade cycle, you might look at purchasing Cisco Refurbished Products.
