An organization intends to shift its legacy customer management system to a cloud provider. The company's priorities are to keep downtime to a minimum and ensure data integrity is maintained during the transfer process. Which approach would be the MOST suitable to meet these requirements?
Implement ongoing data replication between the current and future database systems until the transition is finalized.
Replicate the current infrastructure within the cloud and migrate the application as-is.
Update the system to a cloud-compatible version before migrating to leverage the cloud's native capabilities.
Use a data transfer service to physically ship the data for ingestion into the cloud environment.
