Merging two wordpress blogs with different permalinks ?

Hi guys, ive searched around a number of places and couldnt find the exact answer i was looking for , Im looking to merge two wordpress blogs but both have different permalinks , could anyone possibly help with some .htaccess rewrites so that i can 301 redirect all URL’s of one to the other.

Also the easiest way to do the whole merge ?

The site thats being moved is has post urls like this :

php Code:

http://www.blognumber1.com/this-is-a-post-page/

and the blog its being merged into has URL’s like :

php Code:

http://www.blognumber2.com/category/this-is-a-post-page.html
