Correct answer & explanation
✓
Rehost the application on AWS Mainframe Modernization using Blu Age
AWS Mainframe Modernization with Blu Age allows rehosting legacy mainframe applications with minimal code changes, preserving the existing IMS database and batch processing logic. Option D is incorrect because refactoring to microservices on EKS would require significant code changes. Option B is incorrect because replacing with a SaaS ERP introduces a completely different application. Option C is incorrect because replatforming the database to RDS still requires changes to adapt the hierarchical IMS to relational.
