Been progressively plugging along on my ST to HE migration. Today I was moving my first ZWave device to it. After some exclusion/inclusion trouble I added the device. Then tried to refresh the page and it wouldn't load. Hmm, that's strange. I'm right beside the HE since it was my first device pairing and I notice the LED is off. No big deal, will unplug/replug. No dice. I do not get any color LED to light. Device does not respond to ping.
Ah, it must be the power supply then. No worries, I'll check my bin. I have one with the exact same specs so tried it out - still no LED. Tried different power outlets with no positive results.
I'm early in the migration so I'm not massively inconvenienced and I've been taking backups so I shouldn't lose much work either. But 80% of my motivation to migrate is better reliability which I'm now questioning. (To satisfy any curiosity, the other 20% is to be freed of Samsung's attempts to lock me into their apps & ecosystem.) Any comments on reliability experiences? Did I miss any remaining troubleshooting steps?
First things first, open support ticket! Since you have been taking backups and can move the USB stick to a new hub, if the hub has failed, you just need to get it replaced, connect the old stick, and restore your backup. That should get you back to where you left off.
I don't believe there is anything else you could do, aside from removing the radio stick and see if that might be causing the hub to fail to power up.
Either way, get a support ticket open! support@hubitat.com

Ah thanks for the USB stick removal tip. I think I had read that somewhere earlier as well. Did not resolve it so as you recommend I've opened my first official support ticket. I usually try to figure things out before resorting that!

There's a point, and you reached it when you generously took the time to detail the problems you were having here, when creating a Support Ticket is a good idea. The fact you swapped the power supply means, when I read that, you were already thinking the hub's dead.
Yes, the best support ticket is the one that didn't get created and got figured out. But the 2nd best is the one that is "Oh, thanks, I fixed that already. You can close it." (It improves metrics 
)
It's the parallelism that helps you, in my opinion. Getting Community help is great but getting a replacement hub in TODAY's shipping is going to be better (if that's what it turns out to be.)

You're right, I knew what I had to do and should've done it first. Support is already on it with a replacement being processed. Thanks all.

Not at all the norm, but everything can fail. Fortunately these are not prone to failure and you should be back in business soon.
Welcome. I think you’re going to be pleased with your decision.
Here's how I'm looking at it now - we all know what the backup/restore (non) capabilities are on the old platform. This just allows me to experience how smooth the process is over here

What ended up happening? Same issue here, started getting everything setup and than ran into a Zwave lock that wouldn't cooperate, when I plugged it back in...nothing 
@rylatorr how much time approximately did it take for support to process your request and send the replacement?
I encountered the same thing. Basically I went out the home and after returning I noticed the hub is totally dead (after only 11 days of using it). No LED at all, it's not power supply issue as I tried different plugs etc. I'm afraid I will need to replace the hub. I submitted the request but there's no answer for 5 days now and I'm wondering how much time it usually takes.
Thanks in advance!
did you get an "instant" reply to your email?? If you didn't get the automated acknowledgement, then the Ticket didn't get created properly.. try again. For "dead hub" I'd expect very quick human response because it's a Ticket that reaches "done" quicker than so many others

I did, then I had a very brief chat with Bobby and after it there was this "5 days" - sorry if I didn't make it clear.
Anyway, Bobby has already processed my request today so all good.
Thank you for your help
