Could you please provide a link to definitions for the types of database migrations?
Homogenous database migrations are when you move from one database platform to the same platform…Oracle to Oracle for example.
Heterogeneous database migrations are when you move from one database platform to another completely different platform…Oracle to AWS Aurora for example.
Symmetric, Compound and Synchronous migrations are distractors in that quiz question. They are there to try to confuse you…this is exactly what the exam does occasionally to make sure you know the topics.
