migrating from IP to real url

I am moving my multisite from an IP (https://69.162.148.145/~interlum/) to my real url https://www.interluminaires.com. The problem that I have right now is that whenever I type https://www.interluminaires.com I am redirected to https://69.162.148.145/~interlum/. I changed my DNS this afternoon (Thursday). Was hosted somewhere else before.

I read about how to move my multisite but somehow there are things that are not 100% clear to me right now.

Here is my old wp-config.php :

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
$base = '/~interlum/';
define('DOMAIN_CURRENT_SITE', '69.162.148.145');
define('PATH_CURRENT_SITE', '/~interlum/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

I figured that

$base = '/~interlum/';
define('DOMAIN_CURRENT_SITE', '69.162.148.145');
define('PATH_CURRENT_SITE', '/~interlum/');

need to become (am I right?)

$base = '/';
define('DOMAIN_CURRENT_SITE', 'https://interluminaires.com');
define('PATH_CURRENT_SITE', '/');

what about my .htaccess right now it’s set at :

RewriteEngine On
RewriteBase /~interlum/
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(wp-(content|admin|includes).*) $1 [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(.*\.php)$ $1 [L]
RewriteRule . index.php [L]

what needs to be changed since I am moving from /~interlum to /

what about database I know I have to change references to https://69.162.148.145 to interluminaires.com but is to https://interluminaires.com or https://www.interluminaires.com

I know/hope someone know those answers
