A migration team plans to move a database without checking extensions, data types, or application SQL compatibility. Which approach best fits?

1. Check replication lag and execute the reviewed cutover procedure.
2. Validate row counts, checksums where suitable, and application-level reconciliation.
3. Assess engine features and application compatibility before selecting the migration path.
4. Perform the initial copy, replicate changes, then use a planned final synchronization and cutover.
