Downgrading Smart Zone 100 from 22.214.171.124.250 to 126.96.36.199.222
I have 2 Smart Zone controllers and I spent the whole day trying to downgrade-upgrade the - unsuccessfuly.
They work in cluster, one is leader and the other one is a follower.
I wanted to update them to the latest version however (5.1 or 5.2), however I tried following upgrade path and upgraded them to 188.8.131.52.250. After that I tried upgrading it to newer version but no luck - there was a message that said it is unsupported (I double checked model of SZ, followed upgrade path, tried some other firmwares even from Smart Zone 100-D but no luck).
Now I want to downgrade them back to 184.108.40.206.250 and I did not save any backup because I thought why would I need it since I know how to configure them back in cluster and that is all I need before connecting APs.
Any ideas what should I do? I am worried will all APs models be supported if that firmware version stays on Smart zone controllers. I really do not know why I can not upgrade it.
