BTW, this upgrade will only affect the movie database (VideoDatabaseV?.db3).Automatically exported from code.google.com/p/mediaportal-fanart-handler - mediaportal-fanart-handler/fanarthandler.xmp2 at master · yoavain/mediaportal-fanart-handlergithub.com
I do not have this list, I can say exactly about FanartHandler, LatestsMediaHandler, MPExtended but this is from memory, I do not keep track of plugins that I do not use. But they are obviously still there ...
I'm not sure it's a good idea to rescan 500+ movies, 10,000+ music and about the same number of pictures, not everyone wants to do that. Ideally, you need to migrate from the old database to the new one.
How about TVSeries? mvCentral and other plugins?
Although the infrastructure for the Music, Pictures and Videos will differ, the Music and Picture databases are unchanged.
