Can we mix two license types in a single organization?
MX licensing is uniform across an entire Meraki dashboard organization. For instance, if you have 25 MX networks in your organization, you can have 25 Enterprise or Advance Security or Secure SD-WAN Plus licenses but you cannot have 20 MX devices with Enterprise and 5 MX devices with SD-WAN Plus licenses. For such a requirement, the recommended way of deployment would be to create a separate organization for each edition of licenses.

Note: This requirement does not apply to Z-Series devices or vMXs including the new Z-Series devices that can use Secure Teleworker licenses. Z-Series and vMX licenses can be added to organizations regardless of the MX license type currently applied.
I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.
