help with 301

Hi everyone!
So I have an old site (site A) and a new site (site B).
I`d like to move content from site A to site B because of better metrics. Will copy-pasting the content be seen by SEs as duplicate content if I 301 every page from site A to every page to site B? Also what would be the way to 301 each page? Site A is using thesis, but I don`t know if it`s smart to use their feature to 301 each post. I`m planning to keep working on site A in terms of link building to be able to block ahrefs,etc. on site B.

Any help is greatly appreciated as I`m a bit confused and don't know if this would be a stupid move.

add this on site A .htaccess
and move your site a contents to b with DB and files
that's it ..

Code:

RewriteEngine On
RewriteBase /
RewriteRule ^(.*)$ http://SiteB.com/$1 [L,R=301,NC]

and move your site a contents to b with DB and files
that's it ..

Click to expand...

Thanks, but is there a way to redirect every single page from the old site to the new site?
