Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Incomplete or inaccurate data conversion from legacy systems

Data migration is a critical risk in ERP implementations. Poor data quality from legacy systems can lead to errors, inconsistencies, and business disruption. Ensuring data integrity is paramount.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Inadequate security controls in the new system

    Why it's wrong here

    Security is important but data migration risks are more specific to the implementation phase.

  • Insufficient training of end users on the new system

    Why it's wrong here

    While training is important, data migration poses a more direct risk to data integrity and system functionality.

  • Incomplete or inaccurate data conversion from legacy systems

    Why this is correct

    Data conversion errors can corrupt the new system's data, leading to financial and operational issues.

  • Lack of integration testing between modules

    Why it's wrong here

    Integration testing is important but data migration risks are often more fundamental and harder to rectify post-implementation.
