APs not Joined in a WLC5520 from 5508

[mariajosepicon]

Hi,

I am in a migration. We change the APs from 5508 WLC to 5520 WLC(all APs in local mode).

We configure the Trunk mode in a Port: Switch model WS-C4900M

We change the HA in the APs and We send the APs to New  WLC.

All APs appears in a NOT JOINED

What I can do?
