Reverting MacBook Air 13 inch from Big Sur to Majove using Time Machine backup

Hi all,

Recently, I upgraded from Majove to Big Sur. I have since realized that it was a mistake for several reasons. I want to go back to Majove.

My last Time Machine backup from the Majove system was June 1, 2025.

Is there a way to safely revert to where the computer was on June 1, 2025?

Thanks!!
