I am going to migrate data with the Magento 2 Data Migration Tool. Because the Magento 1 installation I want to migrate has lots of custom tables that come from extensions, I get tons of errors when migrating data. I would be fine to only migrate the standard magento tables.
Do I have to add an ignore statement to the map.xml file for every document I want to ignore? This is a lot of work for me, so my question is, is there any possibility to tell the migration tool to just ignore unknown documents?
My workaround would be to figure out some handy search/replace pattern to generate the xml from the error message I get from the data migration tool.
