Upgrade from 11.5.10 to R12.1.3

Hi,

We are upgrading from 11.5.10 to 12.1.3 and i have been asked to do the following setups.

1. Setup>Purchasing>Document Types

Create the Document type for the Blanket Purchase Agreement [BPA] and assign the same Default Hierarchy as per Existing CPA [Contract Purchase Agreement] Hierarchy

2. Assign the same approval group as CPA where available

--> My question is that are the above steps mandatory for upgrade to R12.1.3 in purchasing and if mandatory what is the process to do it.

Another question is client is using smartforms in iprocurement. I wanted to know if the smartforms will come AS IS as part of R12 and what is the enhancement in R12 for smarforms.
