Upgrading from RPAS 13.3.1.6 to RPAS 15.0.1/15.0.2

Hi All,

We have plan to upgrade from RPAS 13.3.1.6 to RPAS 15.0.1/15.0.2. We go through both 15.0.1/15.0.2 installation guides http://docs.oracle.com/cd/E75729_01/rpas/pdf/1501/rpas-1501_04-ig.pdf  and http://docs.oracle.com/cd/E75729_01/rpas/pdf/1502/rpas-1502-02-ig.pdf and we need clarification on below point.

Current Version

Upgradation Process

Pre 13.3

RPAS 13.3.1 requires a special upgrade process even if you are on major version 13. After installing the code described in “Part II: Patch Installation” of this guide, proceed to either the Classic Client or Fusion Client version of the Oracle Retail Predictive Application Server Administration Guide. The chapter, “Building and Upgrading Domains “, details the full process to convert and upgrade your domain environment to be compatible with RPAS 13.3.1.
