Changing Gateway ID on v3

Is there a way to change the Gateway-ID on TTN v3 after gateway creation ?
I see ttnmapper is looking to have the same id from v2 than for v3 to identify the gateway and place it on the map.
when i migrated my gw from v2, i was may be not enough awake and i put a random name. Now the gateway, although forwarding my packed to v2 application is pure v3 and therefore disappeared on ttnmapper. I would like to fix that cause it seems if the G-ID is the same TTNmapper can sort it out.


But if you are feeling brave you can delete it and add it back in with the ID you want.

But in the grand scheme of things, does it really matter?
