Transitioning to a new chat platform integrated with Salesforce can be effectively managed through various deployment strategies, each suitable based on the specific scenario: A. Phased deployment gradually transitions agents and customers, minimizing disruption. B. Parallel deployment allows running both the old and new platforms simultaneously to ensure continuous service. C. Cutover deployment switches systems during a planned downtime, which is typically scheduled for low-usage times. Selecting the appropriate method depends on factors like the complexity of integration and the organization's tolerance for downtime.
