SAP OS DB Migration of BW to HANA Part 3 - Post-processing

Today, I was at the SAP BW/4HANA official launch in gorgeous San Francisco when SAP announced the immediate release to customers on September 7, 2016.  SAP calls it 'The Next-Generation Data Warehouse', coinciding with the event's co-sponsor AWS who just achieved the latest SAP HANA certification for the X1 instance being able to scale out HANA to 14 TB systems.  Early customers' live testimonials included Fairfax Media from Australia and ConAgra Foods,  Colgate was on stage also, who has been a long-time SAP and BW customer (since I installed the BW 1.0 back then for them - Yes folks, I was there!) currently still on BW on HANA.  The live demo was indeed gorgeous, but the question remains "How do we get there?". 

Well, if you've been reading our blogs, you would have realized that we've already documented the process of getting BW on anyDB to BW on HANA.  Of course, each customer's journey will be somewhat different just as everyone who wishes to visit gorgeous San Francisco may take different paths depending on where they are coming from, the time they have, and the resources and means available to them.  As per the SAP BW/4HANA product page, the Transition journey options include the following, of which we're dealing mainly with System Conversion which is largely based on the SUM DMO we've described.

New Implementation

The SAP BW/4HANA implementation for customers new to SAP's integrated data warehousing technologies will benefit from intuitive modeling and eclipse interface.

The effort for the system conversion is largely proportional to the duration since the last major system update, the number of classical data models, and the amount of actively used custom coding.

• Complete conversion of an existing SAP Business Warehouse system to SAP BW/4HANA
• If your current SAP landscape has been highly maintained (SAP BW, powered by SAP HANA), you can convert to SAP BW/4HANA.

Landscape Transformation

• Ideal for large enterprises with many instances of SAP and non-SAP BW systems
• Consolidation into one global SAP BW/4HANA system or selective data migrations

Here are the 3 parts:

• Part 1: Preparation in the BW System - We documented the collection of references and Preparation steps to make ready the BW system for both upgrade (e.g. Support Pack update) and migration.  
• Part 2: Upgrade and Migration using SUM DMO Tool to perform both the upgrade and migration in one downtime.
• Part 3: Below, we wrap up with the Post-processing on the migrated system.
