Change of project under the same client but different location after my H1B petition got approved


My project got changed (but under the same client) after my H1B petition got approved.

In I129 form, my old project details are there and now to fill my DS 160 form do i have to fill my old project details or the new project details… But both the project is under the same client… There is a catch here, both the project locations are different…

Could any one tell me which details do i have to fill and do i have to provide any other document for this particular situation ?
