  2. ReplatformingAnswer
  3. C
    Refactoring
  4. D
    Retaining

Answer

Replatforming
The correct strategy is Replatforming. Replatforming involves making minor optimizations, such as migrating a self-managed database to a fully managed service like Amazon RDS, to reduce administrative tasks without changing the core application code or architecture.

Step-by-Step Solution

1
Analyze the migration target in the scenario.
The target is migrating an on-premises database to Amazon RDS, a managed service.
This establishes that an optimization (moving to a managed service) is being made to reduce administrative work.
2
Identify constraints on the code and architecture.
The company does not plan to change its core application architecture or rewrite any code.
This rules out refactoring or re-architecting, which requires code modifications.
3
Match the scenario to the correct migration strategy.
Migrating to a managed service without changing core application code is known as Replatforming.
Replatforming is the strategy that involves minimal modifications ('tinkering') to achieve cloud benefits, such as moving to a managed database.
