Finally got the Pi-holes setup again. Went with imaging the SD cards with the newest build. Much easier than the multiple release upgrades I was trying. If I had a cheap way to upgrade to SSDs instead of SDs, I’d try and do it, but would have to do more research. Not sure what else I’d use the Raspberry Pis for though. Realized I also had old configs from the Edge Router Lite or original USG Cloud Key, so I think I can recreate any missing port forwards. Didn’t realize the kids have Friday off. And can’t believe it’s already February in a couple of days. Crazy.
