You may not *have* to replace all your LV machines for each power tier... although I'm sure having all the machines on the same MV or HV cable line would look nicer (and run faster) than some steam-powered machines over near the boilers, some LV machines over here, some MV ones on that cable line over there...
One of these days, I kind of want to put together a HQM pack (probably just Resurrection with a custom HQM config) with easy repeatable quests for basically every GT ore in existence, so I can go through making all the machines and progressing through the tiers without having to mine all the time, which I personally find really boring. Or maybe I'll just spawn in a couple of creative strongboxes and ore blocks as needed, with the self-imposed restriction that I can only use the strongboxes to make ores and more strongboxes (which I can still only use for ores).
That was based on a idea I had back in MC 1.4 or 1.5 that I never got around to in which I would give myself a mass fab, a few stacks of plutonium dust, and an HV solar panel cover.
