How to set up redirects if you use multisite?

Question

WordPress

Good afternoon.
Please tell me how you can set up redirection of the main site to another, if the "multisite" mode is used, so that it does not interfere with other sites on subdomains and does not interfere with logging into the admin area.
tsms: wordpress
Thanks in advance for your answers.

Answer 1

add_action('init',function(){
if(!is_admin() && get_current_blog_id()==1){
wp_redirect("адрес куда нужно перекинуть");
}
});

something like this, enter where you want to transfer the user, you can log in under the superadmin from any site
