Hi, hope you're well!
With mySQL, migrating data is really easy, depending on the size of the tables it could take just a few minutes.
First I would log in to your database via the mySQL interface.
Secondly, we can create a full SQL dump of your database.
Then, when you're ready, you can import that SQL dump back into your new database.
All of the data will be fully intact.
If you'd like to talk more, please don't hesitate to send me a message!
Regards,
Nathan
