# SAP ends legacy ERP conversions after December 31, 2030; the only road left is a rebuild from scratch

> A CTO blog post, published without a press release, dates the moment SAP's Business Suite 7 base stops being convertible: on December 31, 2030, the third-party database and Java support deals die with extended maintenance, and after that the only road to SAP's cloud is a rebuild from scratch.

## The deadline arrived as a blog post

[SAP](https://theinference.org/markets/companies/sap)'s CTO Philipp Herzig [published the end date on the company's own news site on October 7](https://news.sap.com/2026/10/beyond-2030-sap-business-suite-7-sap-netweaver-customers-third-party-databases-java/), with no press release attached: when optional extended maintenance for Business Suite 7 closes on December 31, 2030, SAP's reselling and support agreements for third-party databases and Java expire on the same day [1]. Mainstream maintenance still ends on December 31, 2027, and that calendar has not moved since 2020 [1]. What moves is the plumbing underneath. After 2030, SAP says it will no longer route support tickets to the database vendor, ship kernel or security patches for third-party database environments, or provide database tooling at all [1].

## The cliff feeds the subscription line

Cloud revenue is the engine being fed: it [rose 22% to €6.3 billion in the second quarter](https://www.theglobeandmail.com/investing/markets/stocks/SAP-N/pressreleases/3520956/sap-se-posts-double-digit-cloud-growth-and-updates-2026-profit-outlook-after-q2-results/), the current cloud backlog stands at €22.9 billion, up 27%, and SAP guides 2026 cloud revenue of €25.8 billion to €26.2 billion against €21.02 billion in 2025 [4][5]. The remaining Business Suite base is the last tranche of feedstock, and the post tells it to finish moving, to SAP Cloud ERP and the Autonomous Suite, by the end of 2030 [1].

## The stick followed the carrot by days

The note landed days after CEO Christian Klein [opened SAP Connect in Las Vegas with the Autonomous Suite](https://theinference.org/article/sap-promises-a-historic-ai-windfall-and-its-own-pricing-shows-where-the-deflation-lands): Joule Work live with SAP's own 110,000 employees, productivity gains above 20% claimed in HR, finance and procurement, more than 200 agents generally available and 400 targeted by year-end, with Novartis, Nestlé and PwC named as customers [2][3]. Klein joked that Joule drafts his earnings-call prep so well he asked who even needs a CEO [2]. The blog post carries the other half of the pitch. A system conversion from Business Suite 7 on a third-party database to S/4HANA or Cloud ERP exists only before the end of 2030; after that, only greenfield re-implementations, and NetWeaver AS Java 7.5 drops into customer-specific maintenance in 2031 with no follow-on release [1].

## The rebuild is the expensive road

Greenfield is the long road: [the average greenfield S/4HANA migration runs 20.2 months against 15.8 for a conversion](https://diginomica.com/how-are-erp-customers-faring-ai-readiness-asug-research-reveals-s4hana-migrations-are-accelerating), and 68% of Americas' user group members are already live or moving, with 62% less than three years in [6]. The exposed tail is whoever has not started, and the biggest check in every migration is written to a consultancy, not to SAP.

*Chart: **Integrators take the biggest slice of every S/4HANA migration** Bar chart of S/4HANA migration budget shares: partners and systems integrators 37%, licensing 28%, hosting 20%, building the business case 15%.*

*Share of average S/4HANA migration budget; ASUG survey of 194 members, published October 6, 2026. [6]*

## The escape hatches carry fine print

SAP's bridge, Transition Option for SAP ERP, runs 2031 through 2033, requires systems on SAP ERP private edition on HANA before December 31, 2030, and does not cover Java-dependent capabilities [1][7]. Switching the database to HANA removes the third-party dependency but not the cliff: the system still falls into customer-specific maintenance, which SAP itself says is no sustainable long-term operating model for business-critical systems [1]. DSAG board member Michael Bloch wants any decision based on a comprehensive assessment of all available alternatives, wording that points at third-party maintenance; [Rimini Street](https://theinference.org/markets/companies/rimini-street), listed on Nasdaq, already supports SAP ECC and Business Suite and [sells "no forced migrations"](https://www.riministreet.com/) [1][8].

## Watch the countdown, not the keynote

[SAP reports third-quarter results on October 21](https://www.ad-hoc-news.de/boerse/news/corporate-news/sap-stock-heads-toward-october-21-results-as-backlog-grows/70232870), where backlog conversion does the talking [9]. The trade underneath is plain: integrators book the pre-2030 wave, the database vendors lose the support annuity SAP resold, and holdouts lose the right to convert at all. SAP is no longer selling an upgrade. It is selling a countdown.

## Takeaway

After December 31, 2030, the only road from Business Suite 7 to SAP's cloud is a greenfield rebuild that averages 20.2 months, and integrators, not SAP, collect the biggest share of every migration budget.
