I need some help, when I do a migration with migration tool from magento 1.9.1 to magento 2, I got an error message: "Migration.ERROR: Migration tool exception: XML file is invalid.  ", I was edit the config.xml already with source version = 1.9.1 and destination version = 18.104.22.168 and also delete .dist extension from all xml files inside data-migration-tool folder. Then I perform php migration --config=<path-to-config.xml>, and got this error message, can anyone help me?
I ran into this error and I got it resolved. Within the xml file, there is a reference to a .xsd that defines what the schema of the xml should be. In my case, i ran into the error when carrying out settings migration. So the settings.xsd schema has the definition.
