Final answer:
When upgrading from versions prior to 7.2, the cluster secret must be regenerated or rotated to maintain compatibility and security. The cluster secret is crucial for the system's security and upgrading it ensures adherence to the latest cryptographic standards.
Step-by-step explanation:
When upgrading from versions prior to 7.2, it is important to regenerate or rotate the cluster secret. This step is essential as cluster secrets in older versions may not be compatible with newer releases which can cause issues post-upgrade. The cluster secret is a critical component of the system's security and updating it will ensure that the system is protected with the latest cryptographic standards. To perform this task, you would typically need to consult the official upgrade documentation for the specific system or platform you're working on, as the exact steps can vary depending on the system's architecture and the version you're upgrading to.
