I dumped the Magetno 1.9 database a few months ago. The dumped database was rebuilt in the development environment and the data was migrated to Magento 2.2.
Below is the current problem.
The original Magento 1.9 database was deleted. We then rebuilt the newly dumped database in the development environment and imported the differential data into Magento 2.2, but the data was not migrated.
What should I do in such a case?
