Z4 and Z3 licenses can be mixed?

[andrea.perez]

Hi all,

I have a customer asking for the new Secure teleworker license for the Z4 devices, I know we can mix these licenses regardless of the type of license on the MX but can we mix LIC-Z3-ENT with LIC-Z4-SEC?

Was there any update to this from the support case?

Documentation as of Feb 2026 still states the Z license tier does not have impact the MX license compliance. Only that the Z licenses themselves can not be mixed.

Just had the same issue today with a customer, who read the documentation, and ordered ENT licenses for their new Z4 (like they where used to do on their Z3), but they have MX Adv. so they cant use the license.
I think they will create a case and ask whats going on, because as you mention, the documentation is still the same.
