Delete original configuration instead of replacing
Delete original configuration instead of replacing

I've been experiencing exceptions when replacing the configuration
files. While I never established the root cause, this SO answer
indicated some other process could be accessing the file and causing
issues.

Through trial an error I found deleting the configuration file prior to
moving the new version solved the issue. I've also decided to backup the
original configuration file as it may aid future diagnosis.
