We are upgrading our system using the WebUI. For our custom change we wanted the files in the /etc to also get updated when performing the update. So we have modified the SAVE_CONFIG in the sysupgrade file to 0. After this change we are observing the changes getting reflected. But what we wanted is the files in /etc/ must be replaced when upgraded but it should not upgrade the wireless files.
Is there any method only to retain the wireless files when performing the sysupgrade.
