We have recently moved to CLM 6.0.2 and exploring to use SAFe 4.0 template for Portfolio and Program in our organization. We have gone through several documents available under SAFe section of jazz.net. What we are looking is to use thew 3 level SAFe topology (Portfolio, program & Team) instead of the out of box 4 level SAFe topology that comes with SAFe 4.0. Is there a document or article that helps us on how to use SAFe4.0 to adopt 3 level SAFe topology (I am looking for the guidance on how to use the existing project area created with SAFe4.0 template can be used for 3 level topology).
