Can AP One Enter and AP One Flex roam between them?

On customer site, we have 10 AP One Enter(1 Floor) and 10 AP One Flex(5 Floor). They are managed by HD4. They are different building but they are in the same network. Can we roam between them? For example, one guest comes and use wifi in (1 Floor) and then he is going to 5 Floor. Is it work without any issue. How should I do for that scenario?

If the same SSID and passphrase is set on all the APs the client should roam between them fine.
