11i to 12.2.3 upgrade question about the 11i patch levels needed before the upgrade

Hi,

We are upgrading our Applications from 11i to 12.2 via the 11i to 12.2 upgrade path.

We are aware that customers must meet the minimum baseline requirements per MOS 883202.1.

Our 11i tech stack instance meets these requirements (section 1)

883202.1. Section 1: Minimum Baseline Patch Requirements

However many of the patches in section 2 are not currently applied (have reviewed

most of them, still going through the long list):

Section 2: Products Requiring Additional Patches

(Note: we understand that the patches listed here are for any

apps listed in adutconf.sql as either installed or shared).

Question:

a) Does an upgrade from 11i to 12.2 (and later 12.2.3) require just section 1 compliance,
