Even if they move only part of the data before the deadline ..they stop paying for that the moment they delete it from S3. (Doesn't work that way in reverse.)
They can start saving thousands of dollars even before the deadline if they are able to start moving as soon as their own infra is up and incrementally move and delete data from S3. If their data consumers can work with that, that is.
If part of the data does not need the full S3 guarantees of durability and availability ..they could probably save more by using cheaper tiers while on S3.
