Drupal 7.x

Buenos días, tengo un sitio en drupal 7 pero el que creó el sitio no dejó documentación de las credenciales del multisitio y necesito ingresar para hacer las actualizaciones correspondientes. Tengo los archivos en el cpanel y la base de datos pero no encuentro la manera de abrir el admin del multisitio. 

Good morning, 

how can I upgrade my D7 to D9? I haven't created any website yet (I have one but it's empty for the moment). 

Thank you!

I found the migrate tools avaliable for Drupal 8, 9 and 10 and would like to know if there is something similar for Drupal 7. Thanks

When opening the site the last users details are visible in the login box. I heard 'login register path' would fix it so I tried to download but there doesn't seem to be a Drupal 7 version. Any advice would be very welcome.

Hello, I'm new to working with Drupal and i have to migrate an existing site from Drupal 7 to Drupal 10.
When i go to /upgrade in the modules that won't be upgraded section, i have a big list of them.
Now i'm trying to upgrade the views module but i can't find any patch or how to do it or solve it.
I've been looking at https://www.drupal.org/project/issues/views_conditional and did the same for each of the modules listed, but couldn't find a way to update them
