Why each option
Before connecting a replacement HBA to the fabric, update the alias map with the new HBA's WWN and then activate the zone set to apply the changes.
After updating zoning configurations to include the new HBA's WWN, the zone set must be activated for the changes to take effect and allow the HBA to communicate within the fabric.
Disabling zoning for the old HBA is part of decommissioning it, not a step performed prior to connecting the new HBA to ensure the new HBA functions.
The new HBA will have a unique World Wide Name (WWN); updating the alias map assigns a human-readable name to this new WWN, which is essential for managing zoning based on aliases.
Creating a new zone for the old HBA is counterproductive, as the old HBA is being replaced and removed from service.
Renaming active zones is generally unnecessary; instead, you update the members of existing zones to include the new HBA's WWN.
