[keycloak-user] Migration to Keycloak from WSO2 IS

Hi, Has anyone migrated from WSO2 IS to Keycloak? If yes, what actions did you take to migrate tenants, users, groups and authentication? I'd like to know if anyone done this or have some experience and whether some major issues arised which introduced a lot of difficulties and even stopped them from migrating to Keycloak*.* Any advise and feedback would be very appreciated. Regards, Sinan.
