I had a system migration on my website and approximately 400 links got permanently changed. I'm using the following Redirect in .htaccess file for redirecting old links to new links.
Redirect 301 /old-folder/old-product.html /new-folder/new-product.html
I'm planning to do the similar thing to all 400 links.
My problem: Since I'm all having these Redirect statements in one .htaccess file, will there be any performance issues? Is it okay to add so many Redirect statements in one .htaccess file? Are there any side effects?
Note: there is no fixed pattern in the old and new links so I can't use RewriteRule.
