A company migrates Oracle to a different supported database engine. It needs to identify schema features that require conversion before planning data transfer. Which capability is most relevant?

1. Use DMS full load as proof that all stored procedures and SQL are compatible.
2. Use AWS Schema Conversion Tool assessment and review unsupported objects and application dependencies.
3. Change the database endpoint hostname and keep all engine-specific syntax unchanged.
4. Copy encrypted backups directly between incompatible engines and assume native restore works.
