Transition form factors are uniquely suited to trace the evolution of baryon degrees of freedom by measuring exclusive single-meson and double-pion electroproduction cross sections off the free proton. Recent efforts try to access their isospin dependence by analyzing the cross sections off the quasi-free neutron and proton in Deuterium. In the near future, these exclusive measurements will be extended to higher momentum transfers with CLAS12 and the energy-upgraded CEBAF beam to study the strong interaction where the dressed quark degrees of freedom dominate. Recent and preliminary results will highlight the status of the analyses and an experimental outlook will outline what shall and may be achieved in the new era of the 12-GeV upgraded transition form factor program.
