Hi I'm new to drupal and trying to move the drupal site (version 4.6) from old server to new server. I downloaded the drupal package from official website (version 9.x) when i move the project folder and mysql dump files for database to new server, I can see the static template working, and in the url i can see https://example.com/?q=node/41 and other node values executed with status code 200. But the page is not displaying any data from the database. I can see only the css and frontend codes working without any data.
Not sure if there's a better way for me to phrase this question. Does the Drupal software, including hot fixes, contain codes that were developed outside of the U.S.? I work for a federal agency that restricts server installation of such software. Thanks!
I'm looking for a reference document of some sort that is geared toward experienced Drupal 7 developers who want to have an easy reference for the "new way" of doing various things. Ideally, I'd love to find something that has a before and after reference for all the hooks, functions, and techniques that were standard in 7 that are no longer functional in 9. Something I can refer to when I want to do the things I've done a thousand times before but now its all different.
