Problem moving Wordpress site from one server to another

I moved an existing wordpress site from one server to another.

But when I run it shows database connection error.

In which file do we specify new database related in开发者_StackOverflowformation in Wordpress?

Please let me know.

Thanks!

Database configuration details are located in wp-config.php in the root Wordpress directory.

Here is the official how to for doing this. You'll need to move the files, the database, and likely you'll have to change the hostname in wp-config.
