BizTalk Server · Consulting · Operations · Upgrade
IvaltiCare GmbH, based in Leverkusen, Germany, advises organisations that run Microsoft BizTalk Server in production. Daniel Ivanovic has worked with BizTalk for over 18 years, on single interfaces as well as on entire integration platforms. We find the causes of backlogs and errors, make operations predictable again and prepare the replacement before the end of support forces it.
Services
From the first health check to the upgrade: we work on BizTalk environments in production and measure before we change anything.
We check your environment with the BizTalk Health Monitor and our own SQL queries. You receive a report with prioritised actions. Each action comes with a verification step and a rollback path in case it does not work as planned.
Messages pile up in the MessageBox, send ports slow down, BizTalk throttles itself. We measure first and then make targeted changes, for example to the maxconnection limit in BTSNTSvc.exe.config or BTSNTSvc64.exe.config, to the assignment of applications to hosts or to throttling thresholds. We verify every change with performance counters and netstat before it goes into production.
Suspended messages, zombie messages, hanging orchestrations, databases that keep growing: we find the cause, clean up the backlog in a controlled way and make sure the error does not come back.
We build new interfaces, orchestrations, maps and pipeline components. We deliver them with automated deployment and documentation your team can keep working with.
Support for BizTalk Server 2016 ends on 11 January 2027. If a replacement is not feasible by then, an upgrade to BizTalk Server 2020 provides security updates until 9 April 2030. A direct upgrade is possible from BizTalk Server 2016, while older versions need new servers. Licences should be bought before the expected end of sale on 31 March 2027. Microsoft itself recommends moving directly to Azure Logic Apps. We work out with you which route fits your timeline.
BizTalk Server 2016 end of support →We catalogue all orchestrations, maps, pipelines, ports and adapters and rate them by risk and business value. Microsoft recommends Azure Logic Apps as the successor. We assess with you whether that route fits and deliver the replacement in .NET.
How we replace BizTalk →From practice
Two engagements by Daniel Ivanovic, anonymised.
Daniel Ivanovic brought the BizTalk environment through several versions up to BizTalk Server 2020 without interrupting operations.
Our projects page (in German) lists further engagements in system integration, software development and data platforms.
All projects →Versions and dates
We support BizTalk Server 2010, 2013, 2013 R2, 2016 and 2020, each with the matching versions of SQL Server and Windows Server. Daniel Ivanovic has worked with eight BizTalk versions, from BizTalk Server 2004 to 2020.
BizTalk Server 2020 is the final version. Since December 2025 Microsoft has officially named Azure Logic Apps as the successor to BizTalk Server. Whether that route suits you depends on factors such as where your systems run, how far you already use Azure and your data sovereignty requirements. We assess this with you and deliver the replacement in .NET.
