# Database Migrations
-This page describes database migrations necessary to update existing databases
-to newer versions of Nominatim.
+Since version 3.7.0 Nominatim offers automatic migrations. Please follow
+the following steps:
-SQL statements should be executed from the PostgreSQL commandline. Execute
-`psql nominatim` to enter command line mode.
+* stop any updates that are potentially running
+* update Nominatim to the nwer version
+* goto your project directory and run `nominatim admin --migrate`
+* (optionally) restart updates
+
+Below you find additional migrations and hints about other structural and
+breaking changes.
+
+!!! note
+ If you are migrating from a version <3.6, then you still have to follow
+ the manual migration steps up to 3.6.
## 3.6.0 -> master
+### New location for data files
+
+External data files for Wikipedia importance, postcodes etc. are no longer
+expected to reside in the source tree by default. Instead they will be searched
+in the project directory. If you have an automated setup script you must
+either adapt the download location or explicitly set the location of the
+files to the old place in your `.env`.
