Migration tool released – if you want to consider using the BizTalk WCF adapters.
The WCF-based adapters shipped with the BizTalk Adapter Pack 2.0 are the recommended solutions to integrate various LOB systems with BizTalk Server. The Adapter Pack consists of LOB adapters for SAP, Siebel, Oracle DB, Oracle EBS, and SQL Server. They are built on the WCF LOB Adapter SDK framework. However these are not the first adapters to be released by Microsoft for integration.
The BizTalk Adapters for Enterprise Applications is a suite of adapters based on the older BizTalk Adapter Framework and was released with BizTalk 2006 and BizTalk 2009. Among others, this suite has adapters for SAP, Siebel, and Oracle DB systems. BizTalk Server has a native SQL adapter.
With the release of BizTalk 2009, all these adapters are deprecated in favour of the WCF-based adapters in the Adapter Pack as the latter set has more features and support more LOB versions.
