Question about Orbi Pro SRR60 Router - 162972

Hello, does anyone know if the Orbi Pro is also compatible with satellites from the normal Orbi series? I have an Orbi RBR 50 system and would like to upgrade more. Another question is whether it would be better to replace the Orbi router or just add a Pro 60 Sat. Thank you all for the answer. Greetings Adi
