Do you need to update to Welcome Amiibo to go to another town?

[Biancasbotique]

so here is the scenario:

I have two copies of AC..one has been updated to welcome amiibo and one is not. I wonder if I can still allow people who have updated to welcome amiibo into my town if i need them to go to my non-updated town. Is it necessary for me to update both copies. I kinda want to keep the other one not updated

Hi! I also have two game cards and I couldn't travel between my two towns until I updated my second copy as well. I'm not 100% sure that you definitely have to, but it didn't work for me.
