 VxBlock Central

 Network

 Storage

 Compute

 Virtualization

In the Dell EMC RCM (Release Certification Matrix) Workbook upgrade plan, the sequence of upgrading VxBlock components is designed to ensure system stability and minimize disruptions. Here’s the detailed reasoning for the correct sequence:
