A database migration must minimize write downtime. The source and target pair is supported by continuous migration. Which approach best fits?

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