Understanding the real end to end information flow is needed to thouroughly test and above all correct errors in migrations.

Migration testing of reports depends on the complexity of the information flows e.g. is there a data warehouse or not, and the number of outputs that are to be tested. Such an assignment can take between a few days for simple migrations and a few months when complexity is huge and the number of reports plentiful. The underlying information architecture is an important determining factor in the amount of effort needed…
