When you move a wordpress to a differently named domain, it is not ehough to just search and replace in the database, because wordpress (sadly) store a lot of things in serveral table in serialized format.
So what you need to do is, in your case:
Create a backup of your local database.
Create a backup of your current production database and file.
Delete all the files from your production server, and drop all table from production database.
Copy all files to your production server from localhost.
Import the local database to production database.
Do not open the production wordpress site in the browser!
Go to here, and download the newest script: https://interconnectit.com/products/search-and-replace-for-wordpress-databases/
Unzip it into a wp_replace directory.
Upload this directory to your document root, where wp-conifg.php is.
Go to the http://example.com/wp_replace/
Fill the From and To fields, without http:// and without trailing slash. Eg: somethinog.localhost to 'example.com`
Live run it. You will see, how many records changed in wich tables.
Delete this wp_replace directory. If you leave it, add a htpasswd to it otherwise anybody can crash your db.
Go to the WP admin, navigate to Options -> Permalinks. Push save.
Now you can use your new domin :)
