Upgrading from Fx4 to fx6 on a 75g fish tank

[TGFC]

I have a 75g fish tank and a Fx4 . The cycle is done and the Fx4 has bacteria build already. How would I upgrade from a Fx4 to fx6 without crashing my tank or killing the bacteria? I have all cichlids flametail,red empress,etc all juvenile

Transfer the two FX4 baskets directly to the new FX6. They are the same. To further buffer the transition, you can add Seachem Stability.

I was of thinking that. Everything stays the same . All I will have is 1 new tray. And just switching the old canister .
