[keycloak-user] Migrate from Sql Server users authentication to keycloak

Hello, I have to migrate my user's table in SQL SERVER to Keycloak. We migrate from .NET application to microservices architecture running in minikube. We use postgres to store keycloak data. I would load all my users into the keycloak database. How i can do that? Should I write an implementation of user federation? Is there an option to load data from Sql script into Keycloak database? Environment : minikube (kubernetes)                           User table using SHA512cng -- Hadhemi JEBNOUN
