By lowering the horizontal emittance to about 70 pm rad, the brightness for soft x-rays will increase two orders of magnitude compared to the current ALS. The design utilizes a nine-bend achromat lattice, with reverse bending magnets and on-axis swap-out injection utilizing an accumulator ring. This paper will describe the preliminary plans for the installation of the new three-bend achromat accumulator ring (AR) in the existing tunnel and for replacing the current storage ring with the new nine-bend achromat lattice. The AR will be installed during regular maintenance shutdowns while the ALS continues to operate. The SR will be replaced during a nine months installation period followed by three months of commissioning during the twelve darktime period.
