What are the key differences in schema during SQL migration?
When migrating SQL databases, key schema differences can include changes in data types, constraints, and relationships.
Can you give examples of data type changes?
Sure! For instance, changing a VARCHAR to TEXT or a DATETIME to TIMESTAMP can affect how data is stored and queried.
What about constraints? How do they differ?
Constraints like primary keys, foreign keys, and unique constraints may need to be redefined or adjusted based on the new schema.
How can I ensure data integrity during migration?
To ensure data integrity, you can use validation checks, backup data, and perform thorough testing before and after migration.
