Migration problem

[Lukash4]

After installing the module, when I try to configure it I get the error:

[PrestaShop] Fatal error in module file :/public_html/classes/cache/Cache.php: Uncaught Error: Class 'CacheFileSystem' not found in /public_html/classes/cache/Cache.php:131 Stack trace: #0 /public_html/modules/psonesixmigrator/psonesixmigrator.php(177): CacheCore::getInstance() #1 /public_html/controllers/admin/AdminModulesController.php(868): PsOneSixMigrator->getContent() #2 /public_html/controllers/admin/AdminModulesController.php(1117): AdminModulesControllerCore->postProcessCallback() #3 /public_html/classes/controller/Controller.php(178): AdminModulesControllerCore->postProcess() #4 /public_html/classes/Dispatcher.php(367): ControllerCore->run() #5 /public_html/admin681otycsn/index.php(58): DispatcherCore->dispatch() #6 {main} thrown

How do I fix this to pass the migration?

Prestashop 1.6.1.24
PHP 7.1
