Apps 10 extended support is a planning calendar, not a comfort blanket

29 August 2026 • IFS Expert Inc. (principal) • 7 min read • Apps 10

As of 29 August 2026 the remaining extended-support window is about 19 months to 27 March 2028, and possibly about 7 months to 27 March 2027 if IFS Cloud has been purchased without a demonstrated plan. Those dates come from IFS, not from partner blogs.

The dates (IFS, not hearsay)

Standard support for IFS Applications 10 ended 27 March 2025.
Extended support runs 28 March 2025 through 27 March 2028, then restricted support.

The squeeze

IFS Extended Support Terms (November 2025) add a migration carve-out. If the customer has purchased IFS Cloud and is actively upgrading, Apps 10 extended support can run a maximum of two years from 28 March 2025 (that is, to 27 March 2027) or go-live, whichever is earlier. If they can show an active upgrade plan, it can extend to the 27 March 2028 end of extended support. The same document covers FSM 6 and Alliance 15.4.

If you have bought Cloud and do not have a plan a procurement team would recognise, treat 27 March 2027 as the working date. If you have not bought Cloud, 27 March 2028 is still not far.

This is not a version bump

Partner writing is consistent even where IFS does not publish a methodology: audit customizations and be willing to write them off; do not force Cloud to behave like Apps 10; rewrite integrations toward OData / REST / projections; move Crystal to Report Designer / RDL; budget testing and hypercare, which is where these programs actually fail. Direct technical upgrade from Apps 10 is widely described as supported. Module-by-module exceptions are not certified here. We will tell you what we see in your estate, not a generic path.

What a 90-day readiness engagement actually inspects

Customization inventory and write-offs. Crystal estate. Integration list. "Standard Cloud already covers this" list. 90-day hypercare outline. That work sits inside the Executive Assessment, then a scoped upgrade-readiness follow-on. It is not a greenfield SI bid.

What we will not quote as fact

Partner-reported duration ranges (6-9 months, 12-15 months) are their figures, not an IFS SLA and not ours. Useful as planning colour. Not a promise.
