1. Create CCI configuration definition file A with which to use CCI for pair operations.
2. Perform the pairsplit operation according to configuration definition file A created in Step 1.
3. Perform the pairresync operation without designating a consistency group. Do this using configuration definition file A.
4. Perform the pairsplit operation again using configuration definition file A.
