One of the options for import records will pull in the tables and data one table at a time.
However, the rest of the job is a lot of work.
Any relationships in the original file will need to be re-created detail by detail in the new database. They will need to EXACTLY match your original file in every detail.
Layouts have to be recreated one by one by copying layout elements from your original file and pasting them into your new file.
Scripts have to be imported and checked for correct references.
Then you get to find every button in your new layouts and reconnect them to the right scripts.
