Have you had an USMT job running and you want to exclude a specific file but it keeps on getting migrated? You check your xml file and see that everything is as it should but the file still keeps migrating? Well there is a reason for that. I’m going to try and give you a quick explanation.
Simply put if you have a include of any type somewhere in your xml file(s) then your targeted exclusion will still be migrated. So you can use as many Excludes or Unconditional Excludes as you like, but if you have another Rule section or Component section or etc. It will be included.
