Fidia control retrofit anyone with experience

Hi, We have an FPT LEM 933 mill in out shop which runs on fidia controller, it's of 1995 vintage and there are issues with the setup. we've been in contact with fidia and they have offered an upgrade to newer version and we are considering it. has anyone had experience with the new fidia nc controllers and have any recommendations or even other options we should explore from other providers?
TIA
Mike
