+
+Upgrading from Drupal 7 to 8, 9 or 10 is a large task.
+
+You must create a new empty site, migrate your configuration and data, manually recreate anything else and rewrite any custom modules and themes.
+
+Since Drupal 8, things have been different.
+
+You can upgrade your site in place.
+
+No large code rewrite or data migration.
+
+Many contributed modules support multiple major Drupal versions simultaneously, so they may not need upgrading.
+
+Others may need small changes to remove deprecated code or be compatible with breaking changes, and some tools can automate some or all of the changes.
+
+The same applies to upgrading from Drupal 9 to 10, which will be the same for Drupal 11 next year.
