Ensure every single record that was in Access has found its way into MySQL without any hiccups. Here are key steps you can follow:

Row Count Comparison: Count the rows in your Access tables and compare them against the corresponding MySQL tables. They should match.
Value Checks: Take a random sample of records to ensure that values fit and line up. For instance, if you had a customer's name that read "John Smith" in Access, you’d want it to read the same in MySQL.
Field Type Validation: Pay careful attention to data types; for example, if a field was meant to hold integers, making sure no string data slipped into those fields is paramount.

By following these practices, you can bolster the assurance that the data in MySQL is solid and reliable.

Testing Application Functionality

Once the data integrity is verified, the next logical step is to see how well the application behaves with its new MySQL backend. Think of it like test-driving a car after all the upgrades. Here’s what you can do:

Functional Testing: Run through all the features of your application to confirm that existing functionalities still operate correctly. This means checking every button, link, and page just as you would have in Access.
Error Handling Tests: Inputs that used to work in Access, like unusual characters or large text amounts, should also be tested in MySQL to see how errors are handled or if they crash your application.
Performance Auditing: Measure how quickly operations are performed. If inserting a record used to take a minute and it now takes five, it’s time to investigate.

Getting the application to run smoothly can sometimes take a little tweaking, so keep an eye on performance and look out for slow queries.

Optimizing MySQL Performance

Now that you've established that everything is working as expected, it’s time to milk the system for every drop of performance it has to offer. Here are some recommendations:
