The emergency rollover approach recommended by F5 is to generate a duplicated version of the key with a similar name. This ensures that there is a backup key available in case the primary key becomes compromised or needs to be rotated quickly.
Assigning both versions of the key to the same zone ensures that both keys are available and can be easily managed within the same zone. This simplifies key management and ensures that the backup key is readily accessible when needed.
