htaccess redirect 3rd level folder links except some links

Question

I need to redirect my old site links to new site links as follows.

OLD site Links

Folder level 3

http://mysitex.com/research/000/000/file.php

http://mysitex.com/research/010/008/file1.php

http://mysitex.com/research/000/000/file2.php ....etc more different names links

New links must be,

http://mysitenew.com/research/000/000/file.php

http://mysitenew.com/research/010/008/file1.php

http://mysitenew.com/research/000/000/file2.php ....etc more different names links

NOTE: In above new folder names are not always same to old folder names. Ex: 000/000/files ->>> 010/008 like that. There are dynamic.

So domain name is different and last file name is same and folder's names are not always same to old names. May be change.

Please anyone can help me? Appreciate that. Thanks

Added new.

Here is the contents I'm currently using in the htaccess file.

Options -MultiViews
RewriteEngine On

redirect 301 /research/000/000/ http://mysitenew.com/research/000/000/

RewriteCond %{THE_REQUEST} ^.*/index\.php
RewriteRule ^(.*)index\.php$ /$1 [R=301]

redirect 301 /index.php http://mysitenew.com/

Other contents are normal like above last 301 redirection code and located end of the file.

Thanks

Try this code in your DOCUMENT_ROOT/.htaccess file of old domain:

RewriteCond %{HTTP_HOST} ^(www\.)mysitex\.com$ [NC]
RewriteRule ^research(/|$) http://mysitexnew.com%{REQUEST_URI} [L,NC,NE,R=301]
