I think the rescan is done externally to mythtv-setup using steps defined at https://www.mythtv.org/wiki/XMLTV for initial setup, but I remember that if not careful you can loose Recording rules and previously recorded metadata is some cases.

I will be doing the following steps:
1. mythconverg_backup.pl —backup_xmltvids — # Sometime between now and when channels change.
The created file contains two different formats, the first being a series of update statements using only callsign: e.g.
UPDATE channel SET xmltvid = 'I17155.json.schedulesdirect.org' WHERE callsign = 'Channel 4’;
The remainder are commented out.
After the change has been made, do the following:
2. Stop mythbackend
3. Start mythtv setup
3.1: Clear all the OTA channels currently setup.
3.2. Rescan all OTA channels
3.3 Exit mythtv setup
4. Run the sql update statements generated above.
5. Start mythbackend
