Redirect subdomain to subdomain on new domain

Question

I own 2 domains sio-india.org and sio-india.com

What i want to do is redirect all the subdomains from 1st domain to 2nd domain. eg. home.sio-india.org to home.sio-india.com but i dont want to redirect sio-india.org to sio-india.com and also dont want to redirect www.sio-india.org to www.sio-india.com

Please help

I am using this code in htaccess but it is not working.

RewriteCond %{HTTP_HOST} ^(.*)sio-india\.org$ [NC]  
RewriteRule ^(.*)$ http://%1sio-india.com/$1 [R=301,L] 

Please hepl me I am stuck.

Answer 1

It would be helpful to specify how exactly is it not working. It seems to me that your code would redirect everything (including http://sio-india.org). This is because .* means "any character, zero or more repetitions", so sio-india.org would match too.

You should change your condition to

RewriteCond %{HTTP_HOST} ^(.*)\.sio-india\.org$ [NC]  
RewriteRule ^(.*)$ http://%1.sio-india.com/$1 [R=301,L]

If that doesn't fix it - please be more specific about how it doesn't work.
