This was from yesterday's SAP User Group webinar covering SAP S/4HANA: New Deployment Tools for System Conversions. It was full of new information (at least for me)

The Readiness Check is one of the oldest tools, and has been updated.

The Readiness Check is one of the oldest tools, and has been updated.
Simplification items
Efforts
Resources needed
Extend topic
Deep dive tools to help better assess/predict effort
Activities
Interface analysis - limited to BW extractors and Idocs
- By end of year, may expect new features, new interfaces covered by this analysis
Business Partner is now included in this analysis
-enhancing this tile in readiness check, to give you more information
-customer/vendor records
Working on Finance

Run SUM, send to SAP
SAP has a database, not accessible to public
In that database collect statistics of upgrades/conversions
Collected data
Data by version, system type, productive or QA version
Intend to open data to public
- An app in SAP Support launchpad - suggestions of how to shorten down time
- How long phases take
- How shorten some phases
It is a rough assessment, not a prediction
Will give you an estimate of how long it will be

Custom code
Now a commodity issue
Quick fixes - work in ABAP for Eclipse, automatically fix issues found in code inspector checks
60% automation with quick fixes
30% of code is unused - delete it upon conversion
Remaining with manual adaptation

When do a conversion, a chance to clean up system
If not done in conversion, it will stay in your system
When run sandbox conversion, update UPL or code monitor
Import stats in custom code Fiori App - creates transport

Available in ABAP in SCP

Only available in cloud
Response to question of how to go to back to standard program
SAP developing an approach to this
Measure how difficult it is to read / manage custom code
How often custom code changes
Bubble represent development packages - how difficult to maintain and change
Upper right corner is where money is spent fixing most difficult development packages
Tried with a few customers - picture is the same as above
Up to 1/3 to 1/2 able to find in S/4 to replace customer code

This one is little known
Fix custom code in sandbox, chances to get them to development - this is where retrofit comes into play
Custom code adaptations to feed back in
Helps to stay in sync

Standard conversion - less than 5TB
High end option for large systems - NZDT technology - minimization service - need SAP Services - also available for 1909
Middle option - starts converting to new data structures in up time, records changes, a stable technology, starting 2 years ago; preparing certification for partners so not limited to SAP Services
Bottom part shows a live example - First conversion took 111 hours; then with optimized downtime down to 24 hours
Figure 10 Source SAP
Finance conversion - several table changes, many tables become obsolete as move to universal journal
Tables have inconsistencies in redundancies in old data model
Root causes are different
Run this 3 to 6 months prior to conversion
Figure 11 Source SAP
Business partners are checked for inconsistencies
CVI cockpit - guides you through process of doing CVI

NEW IMPLEMENTATIONS

Can't use LSMW; can still run but not supported or recommended
Use migration cockpit
Data construction - data that you don't have today
Figure 13 Source SAP
S/4 Migration Cockpit
Figure 14
Migrate open items and master data - RFC connection
120+ objects available

What Idoc needed
Uses machine learning and crowd sourcing
Pricing for run time and design time
