    Mod note: This would be better answered on the computer forums. I'll close this down and move it now.

    [Simplification]

    Say the app stores contacts:
    Name, Email

    Now the app is updated to allow phone numbers
    Name, Email, Ph Num

    Its gotta take the old database and add a column to all entries to allow for the new value its capable of storing.

    That migration is that act of fitting the old data to the scheme.
