Coordinator (Z-stack 3) and routers Z-stack 1.2. Is it possible?

Hello!
I decided to change my CC2531 (Z-stack 1.2 ) coordinator with CC2652R1 (Z-stack 3) because I had frequent problems,
which have been solved by flashing of the coordinator. My network consist of around 35 end devices and 5 routes (CC2530+CC2591 Zstack 1.2 ).
The problem is that I can’t pair one router to another. The routers pairing to the coordinator onley. My coordinator is in my basement where
is my server room and it is impossible to pair all routers directly to it, because they are too far away.
Is it the problem of different version of firmware? The Z-stack 3 is it support pairing router with another?
I can’t find Z-stuk 1.2 firmware for CC2652R1, or Z-stack 3 for the routers (CC2530+CC2591).
Any suggestions for solving the problem are welcome. Thanks!
