An engineer is working on a wireless refresh for a customer and identified that the existing WLCs have RTU licenses installed. Which two WLC models can reuse the licenses? (Choose two.)

The Cisco 5520 WLC is the direct successor to the 5508 and is the supported destination platform for RTU license migration, allowing existing AP count licenses to be reused without repurchase.

The vWLC uses a subscription or Smart Licensing model and does not accept RTU license transfers from physical WLC hardware platforms.

The Cisco 3504 WLC is the direct successor to the 2504 and likewise supports RTU license reuse from the 2504 platform, enabling a cost-effective hardware refresh while preserving the existing license investment.

The 5508 is the source platform that currently holds the RTU licenses; it is not a valid destination for migration - RTU licenses flow from the 5508 to the 5520, not to another 5508.

The 2504 is the source platform for RTU license migration; those licenses migrate forward to the 3504 and cannot be re-deployed onto another 2504.
