I have had 5G network, with related router and connected mesh network build with 3xTP Link Deco M9+ devices. Mesh has been on router mode.

I newly purchased optical fiber contract and now I need change and move current network accordingly in to the new optical fiber network.

I just learned I cannot use TP Link Archer routers just because it is not compatible with Deco Mesh network. It would work only by connecting router by CAT wire to Deco mesh.

I concidered to select Deco X20 router. 

How would it be possible to add that X20 in to the existing Mesh network so that it would be router and part of the existing Mesh network and to be Main mesh box?Current 5G network will decommisioned.

Target is that I’d not need reassign all devices assigned in to the existing Mesh network.
