Fresh Start due to major Zone changing

[Monk]

I am adding an ELK-M1XRFTWM device which "must" be installed at address 2. Of course this screws up 3x existing expanders currently installed and changes a bunch of zone numbers in the process.

I'm doing this in the next 30 minutes or so and intend to have the Ultra-M1G3 plugin turned off at this time.
I'm thinking it might be less problematic to just start from scratch / clear out existing plug-in data.
How is the best way to clear existing data?

Thoughts, comments ?

Note to self -
Removing this plug-in for a fresh start was not without issue. On first deleting it, unlike some other plug-ins, all devices are not necessarily removed. Double check that all devices are gone. Some configuration information remains despite best efforts to make sure I could start 100% fresh.
