Return Migration::INFINITE if all units should be migrated at once.

Returns: int

            new \ilDatabaseUpdatedObjective(),
            new ilStorageContainersExistingObjective()
        ];
    }

◆ getRemainingAmountOfSteps()

ilStorageHandlerV1Migration::getRemainingAmountOfSteps ( )

Count up how many "things" need to be migrated.

This helps the admin to decide how big he can create the steps and also how long a migration takes

Returns: int

Implements ILIAS\Setup\Migration.

Definition at line 139 of file class.ilStorageHandlerV1Migration.php.

                                                : int
    {
        $r = $this->database->queryF(
            "SELECT COUNT(rid) as old_storage FROM il_resource WHERE storage_id != %s",
            ['text'],
            [$this->to]
        );
        $d = $this->database->fetchObject($r);
 
        return (int) ($d->old_storage ?? 0);
    }

References $d.

◆ prepare()

ilStorageHandlerV1Migration::prepare ( Environment $environment )

Prepare the migration by means of some environment.

This is not supposed to modify the environment, but will be run to prime the migration object to run step and getRemainingAmountOfSteps afterwards.
