If you're upgrading from a previous release, please read it carefully, or at least skim over it. 0.3.0 ===== This release has one important change. You need to act when upgrading from a previous version! This release changes the database system from MongoDB to SQL(alchemy). If you want to setup a fresh instance, just follow the instructions in the deployment chapter. If on the other hand you want to continue to use one instance, read on. To convert your data from MongoDB to SQL(alchemy), you need to follow these steps: 1. Make sure your MongoDB is still running and has your data, it's needed for the conversion. 2. Configure the ``sql_engine`` URI in the config to represent your target database (see: :ref:`deploying-chapter`) 3. You need an empty database. 4. Then run the following command:: bin/gmg [-cf mediagoblin_config.ini] convert_mongo_to_sql 5. Start your server and investigate. 6. That's it.
