  As a data migration specialist, it's important to be adaptable and willing to learn new systems. In this scenario, I would start by researching the new system and familiarizing myself with its data structure and requirements. I would also consult with the IT team to gain a better understanding of the system and any potential challenges. Additionally, I would create a test environment to experiment with the data transfer and make any necessary adjustments before completing the actual migration.
• 5. How do you handle conflicts or discrepancies between data sets during a data migration process?
  In such cases, I always refer back to the data mapping plan to see if there are any discrepancies or inconsistencies. If needed, I would verify the data with the client before proceeding.

Ultimately, my goal is to ensure the accuracy and completeness of the data in the new system.
• 6. What steps would you take to ensure data security and privacy during a data migration process?
  Data security and privacy are of the utmost importance during a data migration process. To ensure this, I would first conduct a thorough assessment of the data being transferred, classifying it based on sensitivity and implementing appropriate security measures. I would also use encryption methods to safeguard the data during the transfer and regularly test for any vulnerabilities. Additionally, I would adhere to data privacy laws and regulations and obtain necessary approval or consent from the client before transferring any personal or sensitive data.
• 7. How do you handle unexpected technical difficulties during a data migration project?
  I understand that technical difficulties can arise during any project, and I am always prepared to troubleshoot and find solutions. In this scenario, I would first assess the root cause of the issue, consult with the IT team if needed, and clearly communicate the problem and potential solutions to the project manager and client. I am also willing to adapt and make necessary changes to the data mapping plan if needed to ensure a successful data transfer.

Technical Questions
