Redirecting Urls from old website to New - .htaccess

Question

I am trying to redirect my website from old domain to new domain using htaccess. Both the websites have same pages with same url structure i only need to redirect the main url part i-e https://test.com old url to https://test1.com with other pages url as well. For example if i had a page in old website (https://test.com/page1) it should be redirected to (https://test1.com/page1). I used this code to redirect it but its not working any help.
Redirect 301 /page1/ https://test1.com/page1
Redirect 301 https://test1.com

You might find these helpful:
#Redirect from old domain to new domain
RewriteEngine on
RewriteBase /
RewriteRule (.*) http://www.newdomain.com/$1 [R=301,L]
and
#Redirect from old domain to new domain with full path and query string:
Options +FollowSymLinks
RewriteEngine On
RewriteRule ^(.*) http://www.newdomain.com%{REQUEST_URI} [R=302,NC]

The first Redirect has a different source and target URL-path. The old URL has a trailing slash and new one has not.
Then any request beginning with URL-path will return a redirect request to the client at the location of the target URL. Additional path information beyond the matched URL-path will be appended to the target URL.
This means, if you request
http://old.example.com/page1/some/script.php
the path beyond /page1/ (some/script.php without leading slash) will be taken and attached to the target /page1
http://new.example.com/page1some/script.php
To have the complete path appended, you must omit the trailing slash in the old URL-path, e.g.
Redirect /page1 https://test1.com/page1
To address the second Redirect, this will only work inside a Location directive, e.g.
<Location "/page1">
Redirect https://test1.com/page1
</Location>
Finally, when everything works as it should, you may change the status code to 301. Never test with 301.
