  24 =====
  25
  26 This release has one important change. You need to act when
  27 upgrading from a previous version!
  28
  29 This release changes the database system from MongoDB to
  30 SQL(alchemy). If you want to setup a fresh instance, just
  31 follow the instructions in the deployment chapter. If on
  32 the other hand you want to continue to use one instance,
  33 read on.
  34
  35 To convert your data from MongoDB to SQL(alchemy), you need
  36 to follow these steps:
  37
  38 1. Make sure your MongoDB is still running and has your
  39    data, it's needed for the conversion.
  40
  41 2. Configure the ``sql_engine`` URI in the config to represent
  42    your target database (see: :ref:`deploying-chapter`)
  43
  44 3. You need an empty database.
  45
  46 4. Then run the following command::
  47
  48        bin/gmg [-cf mediagoblin_config.ini] convert_mongo_to_sql
  49
  50 5. Start your server and investigate.
  51
  52 6. That's it.
