Welcome to your interview.
The question is on your right: Migrate Data Without Modern Tools. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How would you migrate data across servers if you did not have access to modern big data tools like Spark or Azure Data Factory?
