"""Migration from v0.4 to v0.5, used by `verdi export migrate` command.
The migration steps are named similarly to the database migrations for Django and SQLAlchemy.
In the description of each migration, a revision number is given, which refers to the Django migrations.
The individual Django database migrations may be found at:
`aiida.backends.djsite.db.migrations.00XX_<migration-name>.py`
Where XX are the numbers in the migrations' documentation: REV. 1.0.XX
And migration-name is the name of the particular migration.
The individual SQLAlchemy database migrations may be found at:
`aiida.backends.sqlalchemy.migrations.versions.<id>_<migration-name>.py`
Where id is a SQLA id and migration-name is the name of the particular migration.
