Morning 
just installed the whole voice pipeline on my Pi 4 2GB, and while it runs smooth, it bumped my usual RAM usage from 50% to almost 70%.
Now I was wondering: can I just swap my HA installation to a Pi with more RAM without a re-install, if otherwise everything else stays the same? Iād probably have to update my fixed IP address in my router, as the MAC address changes, but is there anything else? HA runs on HA OS, from a USB-connected msata disk.
Cheers
