Which of the following should be done FIRST when preparing to migrate patient records to a cloud service provider?

Reviewing the current data governance policy is paramount as it establishes the rules, regulations, and standards for handling sensitive data like patient records. This foundational understanding ensures that any cloud migration strategy adheres to legal, ethical, and organizational data protection requirements before technical implementation begins.

Updating the enterprise architecture is a subsequent step that would be informed by the data governance policy, not the first action.

Revising the risk management framework is an important step, but it must be based on an understanding of existing data governance requirements and potential new risks introduced by the cloud.

Defining the service level agreement (SLA) comes after understanding the data's governance needs and designing the service based on those requirements.
