Quoted from "PunisherSy"

old artifacts have lower base bonuses, but still have same skill efficacy, also when you redeem an old artifact the fate elixir and artifact fragments you get will not be enough to craft the same level of the old one that you previously had ( either they don't give back 100% of what materials you've used on old ones, or they've increased the crafting cost for new ones. Not 100% sure). So depending on what you use the artifact for you can keep them or postpone the exchange.
(let's say you have a level 4 old victory cross and what matters to you is the level 4 skill, if you replace it with new one you can't get it to level 4 directly, so what should you do is calculate the amount of material that the old one gives then subtract it from the total needed for crafting a new level 4 one, by that you can tell how much do you need for a full level 4 one. divide that number on how much fragments do you get per week and then you can tell how many weeks do you need to postpone your replacement of the old one to new one).
