The deactivated step template is located in the standard migration folder and provides a template with basic examples for processing the schema and the data. If you want to create a new step, copy this template and adjust the class name, the name of the constructor and the package entry accordingly.
Also, make sure that you adjust all literals to the current requirements. Do not edit the template because it is used as a template for further steps.
Warning
Never set the template to true in the isActive() function. The step would then be carried out at the start of a migration and your data could be damaged.
