Upgrade Nominatim install from 3.6 to 3.7

Nominatim has changed the project structure in 3.7 so we need to migrate the configuration to the new format.

Prequesites

• Stop any running nominatim DB update processes
• Update your linux distribution to the latest version

Install new Nominatim version

root@machine:~$ su - nominatim
nominatim@machine:~$ wget https://nominatim.org/release/Nominatim-3.7.2.tar.bz2
nominatim@machine:~$ tar xf Nominatim-3.7.2.tar.bz2
nominatim@machine:~$ mkdir build37
nominatim@machine:~$ cd build37
nominatim@machine:~/build37$ cmake ../Nominatim-3.7.2
nominatim@machine:~/build37$ make
root@machine:~/build37$ make install
root@machine:~/build37$ apt-get install python3-dotenv python3-psutil python3-icu

This should be enough to get you up and running with the new nominatim tool/binary.

Configuration

Simply create a new empty directory - this will be your new project directory. Then migrate your old settings/local.php to .env file in your project directory with the help of .env.defaults

Migrate database

nominatim@machine:~/nominatim-project$ nominatim admin --migrate

Check database

You can check if the migration went ok and if something else is missing from your database with:

nominatim@machine:~/nominatim-project$ nominatim admin --check-database

And simply follow the instructions if something is missing.

Nominatim UI

Don’t forget to update the Nominatim UI too - configuration and file layout changed a bit, but it’s self explanatory.
