Hi, I would like to connect our AD to the Azure AD. As I see, it needs 2012_R2 functional level. I don't have any Windows AD DC. Is it safe to raise the functional level to 2012_R2 in production environment? I read that 4.19 has initial support for 2019 schema, and for the 2016 functional level, but the 2012 support is still not complete. Thanks, Tamas Pisch
