Restructure of Libraries possible without resetting watched status?

[yshi]

yes, there is a way, i use the trakt plugin for this functionality

i am guessing you are not already using this so when you first set it up go to scheduled tasks on the server and have it export to trakt

Is there something special required for that to work?

I've just created an account on trakt.tv, installed the plugin, restarted the server, clicked on the plugin, authorized my user for the device, popped over to Scheduled Tasks and set uploading to every 15 minutes, and an hour later trakt.tv still claims I've never watched anything.
