From MIUI 10 to MIUI 11

I am on official MIUI 10.3.4 with a patched boot file in order to root the phone, without TWRP.
I have downloaded the official update to MIUI 11. I must install the full ROM to go to MIUI 11 or just the recovery version?

Question Downgrade to MIUI 11?

Is it safe to downgrade Redmi 9T to MIUI 11? Because this phone comes with MIUI 12 as stock rom. Before I downgraded it from MIUI 12.5 to MIUI 12 but I' m not sure about this MIUI 11.

Can you tell me how you did that?
Follow instructions on this link. First update the phone to the latest MIUI 12.5 version and then type "Redmi 9T update tracker" in google and open xda developer site, choose and download two recovery Roms, one you already have ( the latest) and one you want - lets say MIUI 12.0.10. (DONT YOU DOWNLOAD FIRST VERSIONS OF MIUI 12 LIKE MIUI 12.01 OR MIUI 12.02, YOU CAN BRICK THE PHONE. ONLY FROM MIUI 12.08 AND UPPER. MIUI 12.0.10 IS THE BEST I THINK)
After you download them, follow the instructions about update with renaming the MIUI and you will do it.
