Redirect Wordpress multisite to use new domain

Hello, people, I need help creating htaccess redirects to redirect a wordpress multisite from one domain to a wordpress multisite on a new domain. I need to redirect https://domaina.com to https://domainb.com and https://.domaina.com to https://.domainb.com , and https://.domaina.com/ to https://.domainb.com/
Anyone can help me ?

Replying to myself:

#redirect subdomains
RewriteCond %{HTTP_HOST} ^((?!www).+)\.sitea.com$
RewriteRule ^(.*)$ http://%1.siteb.com/$1 [L,R]

#redirect domain

RewriteCond %{HTTP_HOST} ^(www\.)?sitea.com$
RewriteRule ^(.*)$ http://siteb.com/$1 [L,R]

That is what is working for my cyberpanel…
