### Remove the Django Migration Records
After removing the tables created by a plugin, the migrations that created the tables need to be removed from Django's migration history as well. This is necessary to make it possible to reinstall the plugin at a later time. If the migration history were left in place, Django would skip all migrations that were executed in the course of a previous installation, which would cause the plugin to fail after reinstallation.
```no-highlight
netbox=> SELECT * FROM django_migrations WHERE app='pluginname';
id | app | name | applied
-----+------------+------------------------+-------------------------------
492 | pluginname | 0001_initial | 2023-12-21 11:59:59.325995+00
493 | pluginname | 0002_add_foo | 2023-12-21 11:59:59.330026+00
netbox=> DELETE FROM django_migrations WHERE app='pluginname';
```
!!! warning
Exercise extreme caution when altering Django system tables. Users are strongly encouraged to perform a backup of their database immediately before taking these actions.
