Description:
|
|
The task converts an existing SimpleAuth setup to OrmAuth, migrating
|
|
all configured users, groups, roles and rights.
|
|
|
|
Before using this task, make sure your auth configuration is set to use
|
|
the Ormauth driver, you have an ormauth configuration file, and you have
|
|
run all auth migrations.
|
|
|
|
Runtime options:
|
|
-v, [--validate] # Validate the current installation, do not migrate
|
|
-m, [--migrate] # Run the migration
|
|
|
|
Commands:
