rewrite url

[mraza]

hi,

I have a domain over 2k posts indexed.. I wants to change it from

 

http://site.com/category/1021-this-is-title-here.html

to

http://site.com/category/this-is-title-here-1021.html

 

so post id would go at the end with my  new structure. and still if someone visit that old url it will redirect to new url of that post.

 

What should i do to achieve it , i believe something todo with .htaccess

 

Thanks for any help
