Hi,
 
	My isy994i died and I'm considering moving over to a polisy because it is the only option available to purchase. I primarily use it to control insteon light switches and motion detectors via a PLM. Everything else is managed by Home Assistant.  
	Couple of questions: 
	 
 
		Should I start over from scratch and readd all of my insteon light switches to a clean install?
	
	
		Polyglot 2 or 3, if I'm starting from scratch?
	
	
		If I don't start over from scratch, can I import a backup from my isy994i?
	
	
		What else should I be thinking about?
	
	Thanks
