BizTalk Server 2016 and Host Integration Server 2016 end support on January 11, 2027. BizTalk 2020 is the last release, with extended support until April 2030. How BizTalk's pieces (orchestrations, adapters, maps, EDI, BAM) map to AWS services, and a migration order that does not stop the business.
BizTalk sits quietly in the middle of many companies, moving orders, invoices and EDI between systems that were never designed to talk. Microsoft has said BizTalk Server 2020 is the final version. Its mainstream support was extended to April 2028 and extended support runs to April 2030. BizTalk 2016 ends on January 11, 2027.

Microsoft's successor is Azure Logic Apps with Azure Integration Services, and Microsoft provides migration tooling for BizTalk artifacts. If the rest of your estate is on Azure, that is the natural route. If it is on AWS, rebuilding on AWS services keeps the integrations next to the systems they connect, under one identity and network model.
Export every application, port, orchestration and map, and record message volumes per interface. A handful of interfaces usually carry most of the traffic.
Delete interfaces with no traffic in the last year.
Move simple file and message routing first. They are quick, low-risk and build the team's confidence with the new services.
Move EDI partner by partner, running both paths in parallel and comparing outputs before cutting over.
Leave the most complex orchestrations for last, and redesign rather than translate them; BizTalk-era workarounds rarely need to survive.
Once a month: what changed in tech that month and what it means for you, from cloud and AI to security and the tools you build with. Every item links to its source. No sales pitch, unsubscribe in one click.
