How to migrate from Vertikal to Dual polarization ?

Hello.

Now is sector antena Vertikal and all clints are single chain vertikal.
How to migrate to dual chain N clients?

Sector antenna can be replaced with a dual chain model. Some of the clients will have single chain and some of the clients will have dual chain (SXT)

Will this combination clients work on one AP?

This will work.

Clients 1 and 2 (only vertical) are connected to AP on chain 1. It is not a problem?

it will work very good.
