A company runs MySQL database workloads on self-managed servers in an on-premises data center. The company wants to migrate the database workloads to an AWS managed service.
Replatform “lift and reshape”
• Example: migrate your database to RDS
• Example: migrate your application to Elastic Beanstalk
• Not changing the core architecture, but leverage some Cloud optimizations
• Save time and money by moving to a fully managed service or Serverless
The answer is D, Replatform.

This strategy is also known as lift, tinker, and shift or lift and reshape. Using this migration strategy, you move the application to the cloud, and you introduce some level of optimization in order to operate the application efficiently, to reduce costs, or to take advantage of cloud capabilities. For example, you might replatform a Microsoft SQL Server database to Amazon RDS for SQL Server.
Using this strategy, you might make a few or many changes to the application, depending on your business goals and your target platform.
The following are common use cases for the replatform migration strategy:
You want to save time and reduce cost by moving to a fully managed service or serverless service in the AWS Cloud.
In this case, there will be adjustments made due to moving from the database workloads from a self-managed server to an AWS managed service. So that makes it replatforming instead of rehosting. If you rehost, it's just a "lift and shift" without any changes being made.
