Certified in the Governance of Enterprise IT (CGEIT) — Question 167

Which of the following should IT governance mandate before any transition of data from a legacy system to a new technology platform?

Answer options

• A. Data conversion is performed in a test environment to confirm correctness
• B. Data conversion has documented approvals from business process data owners
• C. Control totals of key transaction values are matched with data converted for migration
• D. A crisis management plan has been approved by the IT steering committee

Correct answer: A

Explanation

Option A is correct because testing the data conversion in a controlled environment ensures the accuracy and reliability of the data before full migration. The other options, while important, do not directly address the necessity of verifying data correctness prior to the transition.
