Announcement: Introducing the Logic Apps Hybrid Deployment Model (Public Preview)

anderskingstedt Yes, BizTalk to Logic Apps is one of the core use cases here. There was a previous attempt at building a migration tool but it hasn't been invested in recently. Part of the challenge is that the architectures between BizTalk and Azure are quite different and don't lend themselves to a straight-line migration. But, what we have done is we have invested in Logic Apps that allow you to preserve your customizations from BizTalk. This includes maps and schemas, .NET Framework components (including scripting functoids and business rules. Beyond that we have also implemented better support for XML and added Business Process Tracking (as an alternative to BAM). These investments should reduce the complexity in the migration. 

The migration tool is still useful from a discovery/inventory perspective where it will enumerate all of the BizTalk components that are in use and will help you in your planning activities.
