Hi,
The supplied url for interior page of old domain which you have mentioned not redirecting seems not correct. Because you have linked that text with the new domain. Anyway I have understand your problem. Your problem is
http://www.ccisound.com
is redirecting to
http://www.ccisolutions.com
but
http://www.ccisound.com/StoreFront/category/cd-duplicators
is not redirecting to
http://www.ccisolutions.com/StoreFront/category/cd-duplicators
If I have understood correctly, the solution for your problem is, Do a wildcard 301 redirection. It will redirects all the inner pages to the new domain's inner pages. But all the inner pages in new site, must have the same paths as the old site. Hope you understand what I mean.
Anyway when look in to the example urls you have provided it seems both sites have the same content. So there is nothing to worry about. Seems you have just changed domain name.
So anyway use the following code in your .htaccess file inside your root folder
RewriteEngine on
Options +FollowSymLinks
RewriteCond %{HTTP_HOST} ^ccisound.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.ccisound.com$
RewriteRule ^(.*)$ "http://www.ccisolutions.com/$1" [R=301,L]
First and second line do not write again if those already written inside your .htaccess file.
the above code will initiate a wildcard 301 redirection and will solve your problem. Hope you can improve the code for all the other domains you have. Otherwise post here. I will do it for you.
Regards
Prasad
