  After 20 years of op­er­a­tion, the ESRF has em­barked upon an ex­tremely chal­leng­ing pro­ject - the Ex­tremely Bril­liant Source (ESRF - EBS) . The goal of this pro­ject is to con­struct a 4th gen­er­a­tion light source stor­age ring in­side the ex­ist­ing 844m long tun­nel. The EBS will in­crease the bril­liance and co­her­ence by a fac­tor of 100 with re­spect to the pre­sent ESRF stor­age ring. A major chal­lenge is to keep the pre­sent ring op­er­at­ing 24x7 while de­sign­ing and pre-con­struct­ing all the el­e­ments of the new ring. This is the first time a 4th gen­er­a­tion light source will be con­struct­ing in­side an ex­ist­ing tun­nel. This paper con­cen­trates on the con­trol sys­tem as­pects. The con­trol sys­tem is 100% TANGO based. The paper will list the main chal­lenges of the new stor­age ring like the Hot Swap Pow­er­sup­ply, the new tim­ing sys­tem, how re­li­able op­er­a­tion was main­tained while mod­ern­iz­ing the in­jec­tor con­trol sys­tem and prepar­ing the new stor­age ring con­trol sys­tem, the new his­tor­i­cal data­base, and how ex­ten­sive use was made of soft­ware sim­u­la­tors achieve this.
