If and when one buys a different platform, one can request from FDEV a transfer of assest from the old platforms account to a new different platform account. One looses everything but the total of all one's material objects like ships, mods, and spendable cr's (Total Assests). I'm not sure about pc's but consoles can have multiple accounts, via their platform and just like the original, start as a brand new noob at day one in the sidewinder at the stater system. In the main menu, threre is a process where one can completely wipe their entire status and restart the entire game from scratch and start anew. It comes with a couple of warnings, because it can't be undone.
After 16 months on a ps4, I switched to an xbox one x, requested a transfer from fdev, and though I had billions and billions of cr's, I started the new game which I had to buy for my xbox from the very beginning in a sidewinder as a noob. Though I had billions and billions of cr's, everything else was gone gone gone. No rank, no engineer's unlocked, no permits unlocked, etc etc etc. Obviously, it was a very short time before aquiring my previous ships Python, two Conda's and a Challeger, all of which were immediately "A" graded. But I accumulate any and all materials needed and unlock all my favorite engineer's again. Having been there before, loosing my status of both KING and ADMIRAL wasn't a big deal inso much as I know I'll never need a Cutter or Vette again. I'm a member of the Alliance and thus don't ever have to do those grinds again.
