Do your 3 backups (settings, fav's, watched)
Uninstall old version
Install new version
Restore 3 backups
I also suggest setting up a Trakt account (free) as an added backup and multi device sync.
BTW I have 2 Zidoo X9S Android Media Players. Each has a 500Gb 2.5" SATA hard drive (old laptop drives that were replaced with SSD's). The drives are shared using OpenWRT that runs parallel to Android. Both are connected to TPLink Archer D7 and it's 1Tb USB3 HDD that contains all my music and media files ripped from original media.
