My goal is to take an existing D6 content type ('mini') and migrate it into one of two specific D8 content types based on its current D6 URL Alias (either 'course' or 'page') and where this alias falls in the hierarchy.
I've have successfully written a simple source plugin that adds the alias into RowSource.
How do I control the destination plugin so I can migrate into the appropriate bundle - either 'page' or 'course'? Is there any property of $row that can be adjusted to do so?
Or is this process more involved?
I know that nodes use the 'entity:node' destination plug-in, but how can I extend this per above? It's unclear to me what exact class the destination plug 'entity:node' represents
Any insight would be much appreciated.
