Your old site was backed-up and now your developer needs to restore it on your new hosting environment. After you downloaded the package sent to you, follow these instructions:
Phase 1: Create the Shell
Even though you have the data, your new host needs a "container" to hold it.
Create the Database: In your new host's control panel, create a new database.
Pro Tip: Use the exact same name as the old one if your host allows it (some hosts force a prefix like username_databasename).
Assign a User: Create a user and grant them All Privileges.
Check the Prefix: Open your wp-config.php file and look for $table_prefix. It usually looks like wp_. Whatever is written there must match the prefix of the tables inside your .sql file.
Phase 2: Import the SQL
Now we pour the old data into the new container.
Open phpMyAdmin: Select the empty database you just created.
Import: Upload your .sql file.
Verify: Once finished, you should see a list of tables (e.g., wp_posts, wp_options). If these tables have a different prefix than what is in your wp-config.php, the site will try to start a fresh installation instead of loading your content.
Phase 3: The "Handshake" (wp-config.php)
This is the most critical step. You are telling the WordPress files exactly which "container" to look at.
In your new host's File Manager, edit wp-config.php.
Update the Credentials: Match these to the database and user you just created in Phase 1.
Confirm the Prefix: Ensure this line matches the tables you just saw in phpMyAdmin:
PHP
$table_prefix = 'wp_'; // Change 'wp_' to match your actual SQL prefix
Phase 4: Handle the Files
Upload public_html: Move your folder contents to the new host via FTP or File Manager.
Placement: Ensure the files are in the root (usually /public_html/) and not tucked inside a subfolder
(like /public_html/public_html/).
