If that happens, you are most likely better off starting a clean configuration from scratch, too. However, depending on how old your old release package is, you might still run into hicups.

If you are running an old release package on DSM5.2 and you want to upgrade your DSM and Tvheadend, upgrade your DSM first, only then upgrade TVH with a new release package.
#Dsm etuner install
If you are currently running a Tvheadend-Testing package and you want to install a release package, you will have to start configuring it from scratch anyways. There is some likelihood they are messed up. Otherwise, I recommend clean installations, especially if you have already installed packages from different sources and you have had trouble with user permissions in the past.If you are already running a package, which you have downloaded from here, upgrading should be safe (backup anyway!).I highly recommend staying away from testing packages at the moment, unless you cannot run the release packages for whatever reason and you know what you are doing. The release packages are very recent and up-to-date.Please be patient if the upgraded package does not start right away. The upgrade process may take several minutes as recordings might have to be moved.NEVER run a testing and a release package in parallel. These packages have separate configurations. You cannot upgrade from a Tvheadend-Testing to a Tvheadend release package or vice versa.Always back up your Tvheadend configuration before you upgrade!.All packages provided here are beta packages.Some important remarks for test packages (when available):

Unpublished test packages are sometimes available in this thread, but currently not available. Please report any Synology package-specific issues with the Synocommunity, i.e.

For those interested in native (non-docker) Tvheadend packages for their Synology NAS systems, you will find recent release packages published here:
