That's a take on it I really hadn't considered.  I'm very aware that moving from a decade or two of legacy manual config to full data model/automation in a big bang is never going to work, but I'd been looking at what individual elements could be pulled out and automated with judicious use of "replace".  Never considered making the *entire* legacy config a starting point for the template, and then effectively working on automating replacing parts of that config file with data-driven versions of the same.

Food for thought, thanks for that.
