*urgent* deco m9 (different hardware versions) firmware and ethernet backhaul questions
I have 4 deco m9 plus and bought another m9 recently. 2 of them has v1 and the other 2 and the new coming is v2 hardware. So, 2 v1 and 3 v2 decos.
Thus, i have 2 different firmware versions in my app which are 1.2.10 and 1.5.0 :) (attached image)
My main deco is v2 with 1.2.10 firmware version.
I have the following questions:
1. In order for me to upgrade all of my v2 decos to 1.5.0. what will be the steps to follow?
2. I also want to establish an ethernet backhaul with all of my 5 decos, only 1 will be without ethernet connection and will use wifi backhaul. What will be the proper way in order to do that, first firmware update and then ethernet backhaul or vice versa?
My plan is; first make an firmware update to 3 of my v2 decos but after checking the forum, i guess we can make this only for the main deco if its v2 or am i wrong?
In brief, i need a walkthrough with detailed steps. Your help will be highly appreciated.
