The Migrate module itself contains some excellent examples of data migrations implementing the various APIs provided by the module and serves as the canonical documentation for how to write a migration. In this lesson we'll take a look at the beer and wine import examples provided with the migrate module as a way to familiarize ourselves with the concepts discussed earlier and to be able to see the code that makes up a basic migration before attempting to write our own. In practice these examples serve as a great starting point and can often times be copy/pasted and adjusted for your own needs.
