Hello,
I started this type of projet last year and it’s a heavy project at the end …. (1400 Wyses)
in wnos.ini you can add this line
CCMEnable=Yes CCMServer=https:fqdn GroupPrefix=defa GroupKey=]d`K9G5w CAValidation=No Discover=No
With this configuration all your wyses will arrive in unmanaged group, you keep wnos.ini at the beginning if you are in firmware 8 (3040 for example)
After you have to make modifications in default device policy to transfer wnos.ini settings
Once you have move your wyse to defaut device policy wnos.ini is not used
