+
+One of the first things I do when reviewing whether an application can be upgraded is to look for anything that can be removed.
+
+If it has modules that aren't used, uninstall and remove them.
+
+A common one for Drupal projects is modules left from previous migrations, such as from Field Collections to Paragraphs that are no longer needed but still present.
+
+Remove any old themes that are no longer used.
+
+If you have content types, fields or views that aren't used, remove them, assuming you don't need the data.
+
+Remove unused routes, Controllers or other classes not used in custom modules, or any other unused custom code.
+
+Less moving parts means less to upgrade now and maintain in the future.
