Okay, restored the database, used the --drop_database
--create_database when restoring.
Then I ran the change host values and everything seems to come up.
Now I have copied over one of my recordings and made sure it plays on
the test system.
So at this point, things are looking like the restoring are going to
be just fine.
I have been running into an issue on the test (VM) instance of myth
though. After about a minute and a half, my frontend says it cannot
find the backend.
