Sadly this may not be an option; this is a production server that can at
best stand an hour or so of downtime. Between all the custom symlinked
directories, applications, etc, plus the sheer volume of data that would
need to be backed up, an in-place upgrade would be infinitely more
desirable. If it comes to the point of having to back up and do a fresh
install I suspect I would be using the 6.x series anyway. I was really
hoping that some way of upgrading in-place were available for vinum.
