how to backup live tv

[tvmainia 4]

I thought simply copying liveth.xml from the server I am retiring to the new one would work, but it didn't

I copy and pasted a copy of my old server's "livetv.xml" file from the "config" directory into the new server dir on ubuntu here:
/var/lib/emby/config

but sources, channels aren't getting populated. Nothing appears under Live Tv.

M3u sources, by the way.

Edit:
I did manually change the recording path in the xml file.
Still no go
