htaccess redirect old links to new domain

Question

I changed my site domain, and want to redirect old urls to new domain

(note: instead of numbers 93, 54 maybe any digit number exists) the old urls are:

http://olddomain.com/
http://olddomain.com/45
http://olddomain.com/p/93

the new urls are:

http://newdomain.com/
http://newdomain.com/45
http://newdomain.com/p/93

I tried this at htaccess:

RewriteEngine on

RewriteCond %{REQUEST_URI} 
RewriteRule  http://newdomain.com/

RewriteCond %{REQUEST_URI} (\d+)/
RewriteRule (\d+)/ http://newdomain.com/$1

RewriteCond %{REQUEST_URI} p/(\d+)/
RewriteRule p/(\d+)/ http://newdomain.com/p/$1

but not worked :(

In addition, there is a choice at cpanel caller Redirects can I redirect the old links to new by using it. thanks for help

Answer 1

If it's just those three you want to redirect, you can do it with an OR in your regex. The below should work.

RewriteEngine On
RewriteRule ^/(45|p/93|$)$ http://newdomain.com/$1 [R,L]

Answer 2

This should work:

RewriteEngine On
RewriteRule ^(.*) http://newdomain.com/$1 [R=301]

It will redirect all pages from the old website to the new website.
