I am in final stage of releasing a new version of my website. I have more than 20.000 pages that I must modify the url for.
It is possible for me to make 301 redirects for each of those links? here is an example: as now, my urls are like this: www.example.com/article456.html and after I finish the project, the urls will have this form: www.example.com/title-of-the-article-456.html
do I have to create a 301 redirect in .htaccess for each page?
P.S. I am not askinh on how I can create those redirects but rather if it is ok for .htaccess to handle such a large number of lines.
thank you for your time.
