Replacing content - How to avoid duplicate content penalty?

I have a site A on which I have written one tutorial and I want to transfer this tutorial to my site B. I have already done that and have also redirected my domain A to my site B. However, I'm afraid of that my site B might get a Google penalty for duplicate content - because when I check my site B on copyscape.com it still finds duplicate content on my site A even if this website is already redirected to my site B.

I'm really afraid of getting a duplicate content penalty. Or shouldn't I be afraid at all as the site A no more has the content that it had? But then why does copyscape still find my site A as duplicate of my site B? Should I just wait some time and it will be OK?

 

How are you doing the redirection?

 

I have redirected the domain in my cPanel where my domain is hosted - via the Domain Manager (it is Permanent 301 redirection).

 

So you selected the 'Permanent' redirection option in cPanel? If it's a 301 redirect it's SEO friendly and it should be fine.

Google just hasn't had the time to deindex the old page.

 

Yes, it is Permanent 301 redirection.

Thank you for your quick reply.
