moving from sub.domain.com to www.subdomain.com

while retaining Page Rank and internal links

[sergiomajluf]

Hi, I'm new to this forum, and realize there's lots of information to learn from. So I'm not directly asking for an answer, rather than directons to learn more about this stuff :)

I currently have a wordpress site hosted as http://sub.example.com and all the rewrites to have "SEO friendly" URLs. Now, due to corporate policy, I might have to change to http://www.subdomain.com, so I'll have to move my site.

I already [know I'll lose] --at least temporarily-- my great Page Rank.

I've tried some simple 301 redirects, and ALL traffic to the old site gets redirected to the new's root fine, but I'm looking to accomplish something more elaborate.

Is there a way to redirect, keeping the internal structure? i.e. a redirect that translates http://sub.example.com/category/post/ into http://subdomain.com/category/post/ all the way, working for permalink rewrites and also static files?

BTW, I'm not sure I understand he difference between rewrite and redirect

Thank you all!

Please post your redirect code and tell us where you've installed it as a basis for discussion.
This should be a simple problem, once we know where you've started.
