.htaccess redirect from one domain to another including subdomains

Question

I have two domains, for example:

example.com
website.co.uk

I want to redirect in the following ways:

example.com --> https://www.website.co.uk
alt.example.com --> https://www.alt.website.co.uk
test.example.com --> https://www.test.website.co.uk

As you can see, I want it always to force https and www.

But, I also want it to remember the rest of the URL strcture, for example:

example.com/folder/index.html --> https://www.website.com/folder/index.html
alt.example.com/test/ --> https://www.alt.website.com/test/
test.example.com/o/index.php --> https://www.test.website.com/o/index.php

I'm not sure the best way for this to be done, the two options I found were to try rewrite rules and the other was a 301 redirect.

(yes, the duplicate preserves the protocol instead of forcing https, but this is the simpler case of the two. Just remove the condition and set the protocol to https) — Sumurai8, Dec 20 '15 at 11:43
No, not a duplicate of that because I want it to force the www and https because otherwise there will be 3 redirects as my main site already forces www and https — Ryflex, Dec 20 '15 at 12:08
There is only 1 redirect in the linked question. It is not a perfect duplicate, but the changes are soo minor that I feel like I have to plagiarize the answers there to answer this question. If you understand the directives there, the changes to make your requirements work should be trivial. — Sumurai8, Dec 20 '15 at 12:12

Try the following rules

RewriteEngine on


#redirect subdomains
RewriteCond %{HTTP_HOST} ^((?!www).+)\.domain.com$
RewriteRule ^(.*)$ http://%1.domain2.com/$1 [L,R]

#redirect domain

RewriteCond %{HTTP_HOST} ^(www\.)?domain.com$
RewriteRule ^(.*)$ http://www.domain2.com/$1 [L,R]
