Leaving SAP for Dynamics, Oracle, or NetSuite: the data migration nobody scopes
By Thinklytics Partners, SAP S/4HANA Practice
Some companies are using the 2027 deadline to exit SAP for Dynamics 365, Oracle, or NetSuite. The new platform is the easy part. Extracting, cleaning, and mapping years of ECC data is the hard part.

Frequently asked questions
Why are companies leaving SAP instead of upgrading?
A segment of mid-market organizations treats the 2027 deadline as the moment to exit a costly ecosystem. If they are going to do a major project anyway, some decide to move to a platform they see as nimbler or cheaper to run rather than re-platform within SAP.
Where do they go?
Microsoft Dynamics 365 is the common choice for companies embedded in the Microsoft world, pairing finance with Azure and Power BI. Oracle Cloud ERP attracts larger organizations wanting deep financial forecasting, and NetSuite attracts mid-market companies wanting rapid deployment.
Is moving to a new ERP easier than going to S/4HANA?
The new platform may be simpler to stand up, but the data migration is not easier. You still have to extract years of ECC data, clean it, and map it to a different model. Leaving SAP changes the target schema, it does not reduce the cleansing.
Do you only work on SAP-to-S/4HANA migrations?
No. Our work is the data layer, and it is platform-agnostic. Extracting, cleaning, deduplicating, and mapping legacy enterprise data is the same discipline whether the destination is S/4HANA, Dynamics 365, Oracle, or NetSuite.
What usually goes wrong on a platform switch?
Teams scope the new system carefully and treat the data migration as a side task. Then duplicate customers and vendors, inconsistent codes, and missing fields surface during loads into the new model, and the project slips at the worst time, near go-live.
What is the first step if we are considering leaving SAP?
Measure the real condition of your ECC data before you commit to a target platform or a date. A readiness assessment shows what will be hard to move regardless of destination, so you scope the switch on evidence.
