Involves below major activities

  • Upgrade to SAP ECC, if you are running a lower SAP ERP version
  • Convert to Unicode, if you are running a non-Unicode environment
  • Converting Customers & Vendors to Business Partners as required by S/4HANA
  • Update your current SAP ERP source code to S/4HANA source code

  • Migration of current database (like Oracle, DB2, MSSQL) to HANA database

  • Adapting your custom code to S/4HANA

     

Benefits when compare to other options

  • Lower risk of failure, since it is less complex than other 2 options
  • Lesser downtime, since some migration activities can be carried out while still running your business on the current SAP ERP system
 

  • Less expensive, since you can carry over existing functionality, master data & transaction data

Are you planning to migrate to SAP S/4 HANA from your legacy SAP ERP?

Whatever version of SAP ERP you are currently using, we can help you throughout the complete migration journey from planning, actual migration, post-migration activities & support.

If you are still running a SAP R/3 4.x version, we can first upgrade to SAP ECC when starting the migration to SAP S/4HANA. If you are still running a SAP ERP system in non-Unicode environment, we can convert it to a Unicode environment at the start of migration.
