Thank you for your question! You can change the base URL of your Prestashop by following the instructions in this article. Simply enter www in front of your domain name in the form. (ie: www.example.com). This form will also make the necessary changes in your .htaccess file so you do not need to edit it by hand.
Hi Scott, i have to redirect my old domain to new domain and I first checked your post http://www.inmotionhosting.com/support/website/redirects/setting-up-a-301-permanent-redirect-via-htaccess . Although the post was informative and helpful, but I am bit week in editing the htaccess files, I just purchased a module, https://www.fmemodules.com/en/82-prestashop-url-redirects-301-302-303.html from a store. Here i need bulk redirection from old urls to new urls and this plugin allows to import a csv file for this. As I am not technical enough, please let me know that for the csv file, what should I place in the first column, and second column of that CSV(excel file) so that i can redirect correctly,
I looked through the documentation you linked to, and was unable to find specific information. Since your module has the ability to export a csv as well, I recommend exporting the csv so you can view the formatting.
