Old + new Hubitat models in tandem?

Just wanted to give @brad5 some credit here as he helped with with a similar issue in the following thread:

Help offloading Envisalink processing to another hub

Get HelpIntegrations

“No problem! It was much easier than this will make it out to be, mostly because I'm more than a bit OCD.

I had hub mesh installed, configured, and tested on both hubs before I started. Hint: I got lazy and just enabled EVERY device for hub mesh. More than 500. Big mistake. I suggest you be more judicious than I and mesh only those devices you need. . . .”

@brad5 patiently outlined all the step-by-step instructions to a relative noob (me) on how to off-load some apps and devices to another hub and how to get two hubs meshed at the same time. For those of you not already familiar with this process, this may help.
