+# Upgrade from 1.x to 2.0
+
+## Sonata Admin
+
+* With the movement of all sonata related classes and code from symfony-cmf core bundles to
+  sonata-admin-integration-bundle `sonata_admin` as a bundle set isn't needed anymore. When you still
+  need the bundles defined by this set, you have to register them manually.
+
+## General
+
+* The `LoadBaseData` fixture loader was removed. You have to initialize your test nodes in your own fixtures now.
+* Symfony versions up from 3.0 will be supported now.
+* `Symfony\Cmf\Component\Testing\Document\Content` as a general test document was removed, so you have to create own
+  testing document classes now.
