If you dont want to run it right here or it returns false here, you can do that manually in System > Cache Management and System > Index Management.

4. Migration ResumingWhen a problem occurring on the migration process, Migration Tool provide the ability to resume the process in two ways:

1. Automatically resume on the spot: the tool will automatically resume after a failure until all data is imported.

2. Manually resume: you can refresh the page to go back to Step 1 and click on Resume, this is helpful when you want to temporarily stop migration and resume when you want to.

5. Advanced ConfigurationAccess Advanced Configuration by going to Cart Service Migration > Configuration from Magento backend menu. All default values are configured to work with most cases, thus it is recommended to change these values only when it is necessary to.

XXX Per Batch: Cart Migration splits each entity data into small batches (or chunks) and import them in turn. This option defines batch size to process in each turn. Depending on your Magento hosting resource you can change the values accordingly. The lower the value is, the less time and resource Magento spends to process a batch, also the longer overall time to import full data.Delay Time: the sleeping time between each batch. This option defines the break time for both Source Store and Target Store. It is also helpful to prevent Timeout issue if Source Store has been setup to limit the number of requests in a period of time.Auto Retry After: if by some reason, the batch process fails, the tool will automatically retry after a period of time defined by this option.
