How to migrate from SAP ECC to S/4HANA without overpaying. Conversion contracts, RISE alternatives, indirect access exposure, and the leverage available to enterprises before the 2027 ECC deadline.
The end of mainstream ECC maintenance turns a technical upgrade into a contract reset. License model, price, and digital access terms all reopen at the same moment.
That reset is leverage you can use or lose. The deadline only favors SAP if you arrive without a valued estate and a credible alternative path.
Mainstream maintenance for core ECC runs to the end of 2027, with extended maintenance available to 2030 for a premium. Confirm which date applies to your exact release before you accept a timeline.
SAP times the conversion offer so the credit and the access terms are settled under deadline pressure. The compressed window is what shrinks the conversion credit you are owed.
Your installed ECC licenses are the currency of the deal. Value the full estate, including shelfware, before you accept any conversion figure.
Where ECC migration value concentrates
| Lever | Buyer risk | Buyer move |
|---|---|---|
| Conversion credit | Quoted below true value | Value the whole ECC base first |
| Digital access | Raised after scope locks | Settle terms before signing |
| Path choice | RISE framed as the only option | Price on premise as a real path |
Confirm the product and contract conversion credit in writing. The first quote often understates it, because it values only the licenses you use today, not the full installed base.
The standard advice is to move to RISE now because the 2027 deadline leaves no real choice. We disagree.
In the conversions Fredrik ran, the deadline was the lever SAP used to compress the credit and rush the access terms. Buyers who priced a credible converted on premise path kept the credit intact and settled access on their own timeline.
The buyer side move is to value the estate fully, price both RISE and on premise, and settle digital access before the migration scope locks.
The ECC deadline is SAP leverage, not a reason to accept the first conversion credit you are shown.
Read the migration positioning on the SAP S/4HANA product page and confirm the licensing model on the SAP digital access page before you accept the conversion terms.
Start at least twelve months out and lead with your own license data. The data sets the credit.
Bring help in by month nine, when the conversion credit and digital access terms land together. That combination is where buyers lose the most value.
