In truth, I'm going to have to deal with a shitload of new stuff. I'm going with a Dell or Supermicro server (as in rackable server) with between 8 and 16 disks, so I'm also going to have to deal with new hardware (I suppose everyone kind of has to, since they're not running their usual software). And of course, I'm also doing HomeAssistant stuff on top of that, with all the Zigbee (or whatever other proper protocols I can stick on MTQQ) stuff, or else where would the fun be.
It's a good thing I've been managing Unix stuff for decades (not that it makes me feel any better about juggling a dozen new things at the same time).
