Emby and JellyFin can coexist on the same NAS ?

[niels]

You can have both software at the same time, but you do need to change the HTTP port on one of them from 8096 to something else (you can have only one service for each port).
It is not possible to transfer data from Emby to Jellyfin directly.

Install instructions can be found on our website at jellyfin.org
