Update 2.8.3 to 3.3
Despite my research on the forum, I can't manage to upgrade from my current version: 2.8.3 to the latest version 3.3.
I'm currently in vers php 7.2 that I can update to 7.4 if needed.
Currently my vanilla is operational. To not leave in all directions, can you advise me on the procedure to make a clean update.
I have plugins to activate
Thank you for helping
