integrating existing customer info to SquareSpace

Site URL: https://gems-nc.org/

I'm not sure if this is the right place to post, but I am considering transferring a Wild Apricot hosted site to squarespace, but I am hesitant on the transferring of the customer accounts. I can't find much info about how squarespace handles a customer database, so is this possible to do? Or will I need to get the clients to make new memberships due to lack on integration availability?
