folgendes habe ich zu diesem Thema gefunden..
Die Frage ist ob man nicht einfach die Daten von dem einen in dem anderen Ordner kopieren könnte?

I have made progress.
If you recall, tvheadend on synology saves the config files in /volume1/@appstore/tvheadend/var/
But, as best as I can work out, tvheadend does not look in this directory, but expects the config files to be under .hts in the user directory.
So, I first created a user "tvheadend" via the normal synology process - this creates the directory "/volume1/homes/tvheadend"
I then created a sym link between "/volume1/homes/tvheadend/.hts" and "/volume1/@appstore/tvheadend/var/"
Now, each time tvheadend looks for the config files in /volume1/homes/tvheadend/.hts it is directed to /volume1/@appstore/tvheadend/var/
The above solved my problem.
