[mythtv-users] Multiple hostname changes on DB restore?

[Andrew Cranwell]

I'm currently importing the database from my old BE/FE and am at the 
point of updating the hostname; however, at some point in the distant 
past, I changed the hostname of the old backend without properly 
updating the database (yes, everything broke and I won't do it again).

Is it "safe" to run `mythconverg_backup.pl --change-hostname` twice 
(once with each old hostname)? I tried it and got errors about duplicate 
values, so I'm hesitant to proceed with that unless told it's safe.

Or should I try fixing the damage on the old BE and re-export/re-import 
the DB?
