mysql - migration to and from aws rds -

-

can advise me,

1) if using aws rds, how can seamlessly migrate own cluster of mysql without downtime , data loss?

2) if using own cluster of mysql, how can switch rds without downtime , data loss?

use replication, both new , old mysql sync data, , can shutdown old 1 after import completes.
