Question - if I build out my vlan structure and configuration of my router/switches etc before adding them to my Omada controller, will they all be overwritten or defaulted by the controller?  I see that it will let me keep the WAN settings but no indication if the LAN settings will be kept.   I tried adding it once to Omada, it failed and screwed up my router.  Luckily i took a backup and brought back my conifig but at this point, I don't want to try importing again unless I schedule enough downtime to reconfigure everything if the Controller blows it away.

Any experience/thoughts would be helpful.  I haven't had this problem with the ER7206 but I also typically add the ER7206 at the same time as the Cloud controller.  This was the first time adding pre-configured units to a controller.
