Change category link and redirect the old ones to the new

[RentzRo]

Hi guys, i have a small problem and I'm hopping someone can help me with this:

 

I want to change the links of the categories without modifying the category name

 

www.sitename/OldCategoryLink to

www.sitename/NewCategoryLink

 

this can be done from admin, but how do i redirect all the old links to the new ones?

 

www.sitename/2-OldCategoryLink to www.sitename/2-NewCategoryLink - for the listings and

 

www.sitename/OldCategoryLink/product to www.sitename/NewCategoryLink/product in the products links

 

I'd really appreciate this,

thanks a lot!
