Migration tool

The migration tool is distributed as a standalone jar file named ``db-migration-tool-${corda_version}.jar``.
The migration tool is distributed as a standalone jar file named ``tools-database-migration-${corda_version}.jar``.

The first time you set up your node, you will want to create the necessary database tables. Run the normal installation
steps. Using the db migration tool, attempt a dry-run to inspect the output SQL::
--base-directory /path/to/node --dry-run
java -jar tools-database-migration-3.0.0.jar --base-directory /path/to/node --dry-run
The output sql from the above command can be executed directly on the database or this command can be run::
--base-directory /path/to/node --execute-migration
java -jar tools-database-migration-3.0.0.jar --base-directory /path/to/node --execute-migration
At this point the node can be started successfully.

1. Deploy the CorDapp on your node (copy the jar into the ``cordapps`` folder)
2. Find out the name of the ``MappedSchema`` containing the new contract state entities.
3. Call the migration tool: ``--base-directory /path/to/node --create-migration-sql-for-cordapp com.example.MyMappedSchema``
3. Call the migration tool: ``java -jar tools-database-migration-3.0.0.jar --base-directory /path/to/node --create-migration-sql-for-cordapp com.example.MyMappedSchema``
This will generate a file called ``my-mapped-schema.changelog-master.sql`` in a folder called ``migration`` in the ``base-directory``.
In case you don't specify the actual ``MappedSchema`` name, the tool will generate one SQL file for each schema defined in the CorDapp
4. Inspect the file(s) to make sure it is correct. This is a standard SQL file with some Liquibase metadata as comments.

may be useful. You can run ``--base-directory /path/to/node --release-lock`` to force Liquibase to give up the lock.
