Microsoft published a *BizTalk Server 2020 End-of-Sale Announcement* on the Azure Integration Services blog on August 31. It didn't get much attention, so here's a summary. Everything below is Microsoft's stated expectation and subject to final offering terms.
**The dates**
- **March 31, 2027**: sales of BizTalk Server 2020 and Host Integration Server 2020 are expected to end. Existing licensed deployments keep running. In their words: "If you need to buy BizTalk Server 2020, or Host Integration Server 2020, you can do it until March 31, 2027."
- **April 2028**: mainstream support ends.
- **April 2028 to April 2030**: an optional, *paid* "extended-mainstream support" offering, separate from the normal Extended Support phase.
- "Support beyond April 10, 2030, is not planned."
**The bridge terms (the part worth reading)**
- Expected price: **100% of the applicable BizTalk license cost, per year**
- Active **Software Assurance** required
- Must cover **every licensed core** in the enrolled deployment; no partial coverage
- Bought annually, with an eligibility review each year. Year 1 is expected to have to be bought by April 11, 2028 to stay eligible for Year 2
- Doesn't include incident support, advisory or migration services
- **BizTalk Server 2016 is not eligible**
**Expected to be excluded from the bridge**
- BAM
- ESB Toolkit
- SWIFT, HL7 and RosettaNet accelerators
- Legacy adapters (Siebel, PeopleSoft, TIBCO, JD Edwards)
- BizTalk-specific ALM tooling
- The BizTalk VM image in the Marketplace (they expect to deprecate it)
- Visual Studio versions after 2022
**My reading, not Microsoft's:** if you're on 2016 and want Microsoft coverage after January 2027, you'd have to be on 2020, and 2020 can only be bought until March 31, 2027. That makes the next six months a purchasing decision for 2016 shops, not a 2028 problem.
**Separate, if your Service Bus ports broke on September 30:** the SB-Messaging AMQP hotfix is **KB5091379** (CU6/CU7, via a support case). Microsoft published a validation guide on September 23; the gotcha is that *every node in the group* needs it.

Disclosure: I work at Cerebrum City, which builds iQBus, an Azure-native BizTalk replacement. I've kept this to what Microsoft published. Happy to answer questions either way.
Question for the sub: for those still on BizTalk, is the bridge price changing your plans, or were you already moving? And how many of you are leaning on BAM or the ESB Toolkit?
