htaccess redirect pattern not working

Question

I am using the following code in my htaccess file

Redirect 301 /([0-9]{1,2})+_([A-Za-z])$ /brand/$1-$2

to redirect the following type of URL pattern :

www.mywebsite.com/{ID}_{BrandName}

So basically I have to redirect

www.mywebsite.com/{ID}_{BrandName} to www.mywebsite.com/brand/{ID}-{BrandName}.

For example : Redirect 301 to www.mywebsite.com/5_TestBrand to www.mywebsite.com/brand/5-TestBrand.

Please suggest.

Below is the htaccess code which is not working :

Redirect 301 /([0-9]{1,2})+_([A-Za-z])$ /brand/$1-$2

Please Guide.

Thanks !

You cannot use regex and captured groups in Redirect directive. Use RediectMatch instead:

RedirectMatch 301 ^/([0-9]+)_([A-Za-z]+)/?$ /brand/$1-$2
