The game will make a copy/paste of your account.You will have the same temp on every colony even if it's moved to other pozition like from poz 15 to poz 13.The problem you can have will be with those that you have on poz 8.Will have same temperature but if it's moved to poz 9 or 7 you will get less metal production because it's % production by pozition and not temperature.If moved you get a free relocation but after using the relocation the game will make a new random temperature for the relocated colony.So... those with lower temperature will be fine but not those by the position in sistem.
Another thing that was chenged in the last merge (because i play on other comunity) is that the colony from 15 will not get on position lower that 13. So 15-13 / 12 - 4 / 3-1 ... i did try in the past to move a colony from 15 to 8 by ask a friend to block the sistem so that the game move me on poz 8 but the game moved my colony in the next sistem.
You will get moved in galaxy 5 with a free relocation for every colony moved.
interesting so that must have changed, because eons ago when i was merged from Jupiter to Cygnus some of my planet slots changed and with that the temps (got free relo).
If that's the case it could be a good idea to mention it in the FAQ at the beginning of this thread
