You get the "first" look when pre-conversion training begins. We use your credit unions test data, which has been verified by our conversion team, during the two week on-site training period,  This gives your staff a chance to see it in its converted state.  Also during this time, we have a verification class to make sure the data is converted correctly. On the live conversion, we have an extensive verification process to verify values against the data received. This verification is then reviewed and explained to the CEO for a "sign-off" before any live transactions are processed. Detailed reports are supplied for the credit union's records.
