Hello All there,

Recently I have migrated BizTalk applications from 2013R2 to BizTalk 2020. So after migration the interfaces are running twice as I can see in tracked service instance. In our new environment we have two BizTalk application servers and one SQL Server of BizTalk. BizTalk is installed and configured on both the servers. Host and Host instance are created on Both the servers. Please help us in resolving the issue. Please let me know if more information is needed.

    There are some adapters that you want running on a Clustered Host Instance e.g. that is only running on a single node a time, as these adapters have no mechanism to prevent picking the messages up at the same time.

    These include

    • POP3 (possibly also the new Office 365 Mail adapter)
    • WCF-SQL
    • FTP(s)
    • SFTP
    • MSMQ
    • SAP
    • receive adapter that supports ordered delivery

    See Clustering Receiving Hosts
