optiwindnet.db.migrate
======================

.. py:module:: optiwindnet.db.migrate

.. autoapi-nested-parse::

   Migrate a v2 (Pony ORM) or v3 (Peewee) database to v4 (Peewee, slim RouteSet schema).

   Uses sqlite3 to read the source file (no Pony dependency), writes v4 with
   Peewee. The RouteSet field `num_gates` is renamed to `feeders_per_root`,
   and the columns dropped in v4 (`valid`, `is_normalized`, `stuntC`) are
   discarded.

   Usage:
       python -m optiwindnet.db.migrate input.sqlite output.v4.sqlite
