Keep watch history when changing drives?

[tmsrxzar]

when you install trakt on the existing setup you will "export library to trakt"
then when you reinstall, after rescraping, you will "Import watched states and playback progress from trakt.tv"

then everything will be as it was on the old install

if you keep it active it's configurable to track per user account and if the server ever gets reset you can always import again, it's rather handy
