 # Database Migrations
 
-Since version 3.7.0 Nominatim offers automatic migrations. Please follow
+Nominatim offers automatic migrations for versions 4.3+. Please follow
 the following steps:
 
-* stop any updates that are potentially running
-* update Nominatim to the newer version
-* go to your project directory and run `nominatim admin --migrate`
-* (optionally) restart updates
+* Stop any updates that are potentially running
+* Update the backend: `pip install -U nominatim-db`
+* Go to your project directory and run `nominatim admin --migrate`
+* Update the frontend: `pip install -U nominatim-api`
+* (optionally) Restart updates
+
+If you are still using CMake for the installation of Nominatim, then you
+need to update the software in one step before migrating the database.
+It is not recommended to do this while the machine is serving requests.
 
 Below you find additional migrations and hints about other structural and
 breaking changes. **Please read them before running the migration.**
 
 !!! note
-    If you are migrating from a version <3.6, then you still have to follow
-    the manual migration steps up to 3.6.
+    If you are migrating from a version <4.3, you need to install 4.3
+    first and migrate to 4.3 first. Then you can migrate to the current
+    version. It is strongly recommended to do a reimport instead.
+
+## 4.5.0 -> master
+
+### PHP frontend removed
+
+The PHP frontend has been completely removed. Please switch to the Python
+frontend.
+
+Without the PHP code, the `nominatim refresh --website` command is no longer
+needed. It currently omits a warning and does otherwise nothing. It will be
+removed in later versions of Nominatim. So make sure you remove it from your
+scripts.
