    Hi @Dario Alexander agudelo gallego

    Perhaps multiple migration attempts caused duplicate files in the site collection (even if they were different subsites).  Deleting the subsite still left the files in the site Recycle Bin.  Needed to delete them from the Second-stage recycle bin as well.

    Please try and let me know the result?
