If so, you must explicitly configure the unique "feeder ID" that your feeder will use so that your existing site is preserved and you continue adding to the same site statistics on the My ADS-B page. (If you do not configure your feeder ID, then a completely new site will be created.) If you can move the existing SD card to the new device then you do not need to do anything special.

If you want to move your feeder ID to a new installation of PiAware:

1. Your new installation must be on the latest PiAware software. If it is not, upgrade it first (or flash the latest SD card image).
2. Find the existing feeder ID that you want to use. You can find this either as the "Site Identifier" on the site's statistics page (My ADS-B) or from the PiAware logs in /var/log/piaware.log on your existing install. The identifier looks like a series of dash-separated hex digits, e.g., 12345678-1234-1234-1234-123456789abc.
3. Configure the feeder ID on the new system by running this command on the Pi:
   piaware-config feeder-id 12345678-1234-1234-1234-123456789abc
   Or, edit the piaware-config.txt file to add the feeder-id configuration row:
   feeder-id 12345678-1234-1234-1234-123456789abc
4. Restart the device or restart piaware by running this command on the Pi:
   sudo systemctl restart piaware
