問題文
What belongs in a sound migration plan for existing contracts and assets?
選択肢
- A single untested bulk load straight into production with no reconciliation and no way to undo it, so the first real exercise of the migration is against live data that billing and customers immediately depend on with no fallback available.
- Loading just expired records that need no action, so the migration deliberately avoids the active contracts and assets that must be renewed and amended after go-live and brings across only data no one needs to work with.
- Choosing what to migrate by record color, so that whichever records were flagged in the brightest shade are loaded into production first, and the paler records follow in a later pass.
- A staged load mapped to the new model, reconciliation of counts and amounts, and a rollback path if production goes wrong.
