System Role change in Solution Manager 7.2

Hi All - I understand that the way Dual Landscapes were managed long ago, by changing systems roles to flip between project and maintenance system roles has been discontinued, however we are implementing Charm in solution manager 7.2 and want to switch the system roles in future. I.e . systems in maintenance branch will be moved to development and vice versa. Are there any issues associated with the process and is it possible in 7.2?
