For this application, stay away from the File Streaming API. It uses record databases
as it's underlying representation. All the record sizes are fixed at 1024 bytes (not
officially stated anywhere, subject to change, yadayada). Unless your upgrade is raw
data this probably isn't a good fit.
You'll probably want to open a new resource database and construct the resources
yourself from the data you receive.
