Hi there,
I am preparing for the Drupal 8 → 9 upgrade and tried to make a clone of the official site to test everthing.
Here is our site: https://ams02.web.cern.ch/ ,which was built originally on the old infrastructure. There are several modules installed under the _webdav folder, instead of using Composer.
So, I created a cloned site via the new web interface by adding a new environment, as instructed in
https://drupal-community.web.cern.ch/t/create-a-drupal-9-clone/1346/3
This is the test site: https://ams02test.web.cern.ch/ , I found it crashes, and I checked that all the modules and themes are not cloned under the _webdav folder of the test site.
Could you help me by clarifying what is the proper way to create a test site? We did a lot of customization to this site and would like to make sure the upgrade can go smoothly.
Thank you in advance!
