Unable to make a 301 redirection from siteA.com/* to siteB.com/*

Question

I just moved my site from siteA.com to siteB.com. There are hundreds of articles published in siteA.com.

Google finds still only articles on siteA.com.

Example of the problem

I can find the following articles in Google

www.siteA.com/article1
...
www.siteA.com/article777

I need to make make 301 domain redirection from each article at siteA to siteB's articles such that

www.siteB.com/article1
...
www.siteB.com/article777

This would require 777 domain redirections in .htaccess.

Is there any easier way to make the domain redirections than writing 1555 lines of code in .htaccess -file?

Answer 1

Why 777 domain redirections? Just put:

Redirect permanent / http://www.siteB.com/

into the .htaccess file in the document root of www.siteA.com.
