Comment 40 for bug 1463480

@jjo yes when storing in 1.20.14, juju does not know about the configuration option, but is happy to store it.

When the upgrade happens and the value is then read, it is converted to a bool (at least it appears to be when tested locally).

@peter-sabaini when trying from 1.22.6 -> 1.24.6 did you set the value in the environment before attempting the upgrade?
