If you have DB access of production , 

The pega database schemas provide 3 functions to read properties from the storage stream:

• pr_read_decimal_from_stream
• pr_read_int_from_stream
• pr_read_from_stream

Each function has 3 input parameters:

• property – String, the name of the property to extract
• inskey – String, the pzinskey value of the record to read from
• storage_stream – Byte array, the actual storage stream to read from

For example 

SELECT pegadata.pr_read_int_from_stream('MaximumIncome','DMORG-DMSAMPLE-WORK A-3',(SELECT pzpvstream FROM

pegadata.pc_work_dms WHERE pzinskey = 'DMORG-DMSAMPLE-WORK A-3'))
