I am new in WordPress. I am trying to migrate a WooCommerce site. What are the steps to Migrate a WooCommerce site? Where is the location of `.htaccess` file in a WooCommerce site?

I migrated files and databases. I changed setting in `wp-config.php` file. I changed site URL in `wp-options` table of the database. But I found that my migrated site is not looking like the previous site, even I am getting `Not Found` error while I am trying to browse categories pages.

Could anyone say where is the issue ?
