You did not indicate whether you are moving your blog from myolddomain.com to mynewdomain.com, and whether you are using normal WordPress or multi-site WordPress. But here are some tips that might help:

• First, you need to make sure your wp-config.php is configured correctly (database server, username, password...)

• Secondly, WordPress uses database to store some information about the current host, look at tables wp_site, wp_options,wp_sitemeta and replace all rows containing myolddomain.com by mynewdomain.com.

• Make sure your EC2 security group is configured correctly.
