Hi,
We are working on a solution of migrating a datawarehouse from Informix to Teradata. We are looking for what can be the high level challenges while this migration - specifically from Physical Modeling perspective (we need to take care of the PI,PPI,JIs etc.) - anything else- a best practice guideline will help immensely. Also any other challenges like incompatible data types etc.
A direction to some best practice guidelines or any personal experience will be helpful
