The following illustration shows a high-level view of the migration process.
An AWS DMS replication instance performs the actual data migration between source and target. The replication instance also caches the transaction logs during the migration. The amount of CPU and memory capacity of a replication instance influences the overall time that is required for the migration.

Creating replication instance will take several minutes. While waiting for the replication instance to be created, you can specify the source and target database endpoints in the next steps. However, test connectivity only after the replication instance has been created, because the replication instance is used in the connection.
