TerraGrow Agriculture is planning to migrate its legacy on-premises applications to the AWS Cloud. The company has identified two specific workloads for the first phase:
1. A proprietary crop-yield analysis application that must be moved immediately to AWS with absolutely no modifications to its code or configuration.
2. An on-premises legacy customer relationship management (CRM) database that will be decommissioned and replaced with a modern cloud-based Software-as-a-Service (SaaS) platform.

Answer
Rehosting and Repurchasing
Rehosting and Repurchasing are the correct strategies. Rehosting, often called 'lift-and-shift', moves workloads to AWS without modifying code or configuration, aligning with the crop-yield application requirement. Repurchasing, or 'drop-and-shop', replaces legacy systems with new cloud-native Software-as-a-Service (SaaS) products, matching the CRM replacement requirement.
