What is the first step when preparing for a VPLEX hardware upgrade?

Conducting pre-upgrade health checks is a critical first step in preparing for a VPLEX hardware upgrade because it ensures that the existing system is in good working condition before any changes are made. This process involves assessing the overall health of the VPLEX environment, checking for any issues that could impact the upgrade, and confirming that all components are functioning properly. By identifying and resolving potential problems beforehand, you help to minimize risks during the upgrade process.

Ensuring a smooth and successful upgrade relies on having a solid foundation to start from, which is why health checks are paramount. Taking this approach not only improves the likelihood of a seamless upgrade but also helps in maintaining system integrity and availability throughout the process.

The other options are subsequent steps that depend on the assessment and readiness determined by the health checks. For example, running hardware upgrade scripts, installing new hardware, and reviewing hardware compatibility are important, but they should only occur after confirming the system is healthy enough for an upgrade.
