What is the first step in the Local to Metro upgrade process?

In the Local to Metro upgrade process for VPLEX, the first step is to upgrade the existing cluster. This step is fundamental because it ensures that the environment is running a compatible version of the software before introducing new components or configurations essential for Metro setup.

Upgrading the existing cluster prepares the system for the transition to the Metro configuration, as it aligns the software levels across different components. This is crucial for maintaining stability and compatibility throughout the upgrade process, as any deviations in the software versions could lead to complications or failures during the integration of the local cluster into the broader metro architecture.

This step is foundational because subsequent actions, such as backing up metadata, cabling WAN connections, or running I/O module upgrade scripts, depend on having a fully updated and stable cluster environment in place. Each of these tasks would follow logically, ensuring that system integrity is upheld throughout the upgrade journey.
