Minimizing Business downtime converting to SAP S/4HANA®

Publish date:

As confirmed during our different S/4HANA Conversion live experiences, one of the main drivers influencing the S/4HANA migration path is the business downtime: how many hours Businesses accept to stop day-by-day activities allowing that S/4HANA conversion happens on productive environment?

Business downtime plus technical downtime determine a window where, typically during the weekend, our customers interrupt activities on SAP ECC side to be able to restart business transactions on the renewable SAP S/4HANA®. Usually small & medium sized companies accept more flexible stops, large companies impose very short time and, in some cases, ask for a progressive movement (company-by-company, region-by-region, etc) or ask for a subset footprint on data conversion.

How do we manage these scenarios? We have different options to put in place.

As we know, converting to SAP S/4HANA, business & technical downtime run-time are determined by database footprint and functional activities like SAP S/4HANA Finance activation with CVI Business Partner conversion:



How to minimize business & technical downtime?

  1. Anticipate CVI Business Partner conversion on SAP ECC side in silent mode: yes, it is possible to anticipate on the SAP ECC side the CVI conversion applying a “silent mode” conversion during the business-as-usual. In this case, when SAP S/4HANA Conversion will run, Business Partner will be already in place
  2. Anticipate Pre-Check functional verification: yes, it is possible to anticipate check and resolution of master data and business document on SAP ECC side. In this case, when SAP S/4HANA Conversion will run, Pre-Check will solve faster the phase
  3. Archive business document no more relevant; purge technical non-used data from standard table. Usually different Gigabyte – in some case Terabyte – of data are persistent on SAP ECC database without any business values
  4. Apply NZDT Near-Zero-Down-Time SAP Service to convert with “delta reply” your SAP ECC database to SAP S/4HANA new data-model during business-as-usual activities without business interruptions, having the opportunity to convert more than 10Tb in few hours
  5. Apply SAP SLO Service to convert company-by-company, region-by-region or converting a subset of your SAP ECC database
  6. Apply the new SUM-NZDT option available starting from SAP S/4HANA 1909 toolkit to anticipate data-model conversion in uptime window

As we have different options to reduce downtime, it means we have the opportunity to consider a “move-to-cloud” approach in conjunction with SAP S/4HANA Conversion, the “en plein”!
