Method 1

You appear to be missing some files. There should be an index.php file in that root directory for example. Try downloading a fresh copy of WordPress from http://wordpress.org/wordpress-5.6-no-content.zip and upload the files from that zip to your new server

Method 2

You’ll also need to update the URLs in the database, I run the following sql query in phpmyadmin > database > query after a migration.

swap wp_ with your db table prefix if different from default, & adjust any URLs as needed:

UPDATE wp_options SET option_value = replace(option_value, 'oldurl.com', 'newurl.com') WHERE option_name = 'home' OR option_name = 'siteurl';
UPDATE wp_posts SET post_content = replace(post_content, 'oldurl.com', 'newurl.com');
UPDATE wp_posts SET guid = replace(guid, 'oldurl.com', 'newurl.com');
UPDATE wp_postmeta SET meta_value = replace(meta_value,'oldurl.com','newurl.com');
