Following on from what Walter @krambriw said... One of our beta-testers has HSS running on a RPi-3B.

I'm running HSS on a RPi-4B with 2GB of RAM, Node-RED v2.0.5 with Buster OS.

I spent over 3-hours a month ago bringing one of my Pi(es) up-to-date as Node-RED v2 requires Buster.  
I had to go from Jessie to Stretch and then Stretch to Buster (what a pain).  
**If I had to do that again, I'd just back-up the old Pi and flash a 'new' SD card with Buster.**  
I posted my experience on the forum.

> I'm trying to grade a RPi-3B, running Buster, to Node-RED 2.0.5 After the upgrade Node-RED gives loads of error message, I suspect because nodejs is still v8.17.0 I used this bash script. This is a screen-shot of the update report. [Screen Shot 08-25-21 at 10.05 AM] Any suggestions on what I could try next to update Node.js to v12 ?
