# This migration takes all legacy uploads (that were uploaded using AttachmentUploader)
# and migrate them to the new (FileUploader) location (=under projects).
#
# We have dependencies (uploaders) in this migration because extracting code would add a lot of complexity
# and possible errors could appear as the logic in the uploaders is not trivial.
#
# This migration will be removed in 13.0 in order to get rid of a migration that depends on
# the application code.
