@dahukanna "Moving house" is an interesting metaphor, mostly because no matter how you do it, it's a lot of work.
Couldn't changing a server be more like "changing SIM cards"? You make a call, port your number over to another company, put it in, and things "just work."
Not a perfect comparison, but something closer to what I'd like changing servers to feel like.
@scottjenson
I agree it should be like a “SIM-card switch” but there is no personal, edge-device, only a server in a data center. That’s why It’s a “device replacement” rather than a “SIM-card switch”The “edge-device” equivalent for the person is missing.
