I think this would have to be combined with universal healthcare. If basic income is enough to live on barring any medical issues, then universal healthcare would take care of the medical issues part.
As for social security, it would have to be slowly phased out. The people on it now and the still working have been paying into the system, and should at least get there money back plus interest.
