Tvheadend

h1. Migration

If you want to migrate between Tvheadend instances, one possible approach is to configure your new instance in advance, reading your muxes via http. Of course if you have a large number of muxes, just loading on by one could be tedious, so it's better to do it programmatically. Refer to the attached script.

This script has been tested on migrating a 3.4 server to a 3.9 server.
