I have to redirect over 14K urls from another system to magento core_url_rewrite. What is the preferred method, to place these urls in database, or to redirect the ursl from .htaccess file ?
htaccess is good Idea .But it is too tuff write code for 14k urls in a htaccess file,
Better idea to rewrite using magento code and that case ,you can use 3rd party extensions like
Optimise Web's Mass 301 Redirects for 404 Pages is best as per as my thought
