Covast has developed an accelerator to help with migration of Gentran maps to BizTalk.  Covast is producing a webcast to describe the accelerator.  If you are interested, you can find more information at Covast.com.  Webcast dates are Jan 26th, Feb 10th, and Feb 24th.  Register for the webcasts here.  Please let me know if you need other migration information to/from BizTalk.  What other capabilities are needed right now, or need to be discussed?
