I did extensive search on data migration/porting testing in this forum. I am happy to see lot of valuable information.

None of these topics deal with complexities of data migration efforts involved when two huge COTS systems are involved.

My back ground is in product development. This is a new challenge for me. I just joined a team with little test preparation who are in the middle of a huge data migration effort from JD Edwards and PeopleSoft to Oracle e-Business suite. I have been tasked to lead the test effort.

I would appreciate any thoughts or experiences that would help me in planning this effort. Pitfalls to watch out for are a big plus.

Thank you in advance for your insights.
