问题 I have the source code of BizTalk 2010 applications that needs to be re-written for BizTalk 2013. What i am doing so far is that I am creating new BizTalk 2013 project, adding the existing files from 2010 project (schemas maps orchestrations pipelines etc.) and compiling and building the project (fixing the errors on the way).
