Repurchase

Migration strategy that replaces an existing application with a different product, typically a SaaS offering; also called drop and shop.

Definition

Repurchasing retires a self-hosted application in favor of a commercial or SaaS product, such as moving from an on-premises CRM to Salesforce. It often involves data migration, retraining and new licensing models.

Example

An on-premises Exchange server is replaced by Exchange Online in Microsoft 365.

Exam tip

Moving to a SaaS product equals repurchase.
