Migrating from subdomain to main.

[skepas]

Hello everyone,

well as the title says, im trying to move from old.domain.com to domain.com. The problem here is, I have made a new database, I have made backup of old db and files, uploaded them to new domain and get an 500 error. Also I can't connect to admin panel becuase of
 

Link to database cannot be established:SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known
at line 102 in file classes/db/DbPDO.php

97.     public function connect()
98.     {
99.         try {
100.             $this->link = $this->_getPDO($this->server, $this->user, $this->password, $this->database, 5);
101.         } catch (PDOException $e) {
102.             throw new PrestaShopException('Link to database cannot be established:'.$e->getMessage());
103.         }
104. 
105.         // UTF-8 support
106.         if ($this->link->exec('SET NAMES \'utf8\'') === false) {
107.             throw new PrestaShopException('PrestaShop Fatal error: no utf-8 support. Please check your server configuration.');

Do you have any suggestions?

Your settings for the database connection in the /config directory is wrong. Maybe you still use the old settings file which isn't valid any more? Furthermore you have to change your base domain in backoffice - settings - url & seo and rewrite the .htaccess file.
