A company, XYZ, is looking forward to change things around with client/server infrastructure to support mobile clients and more laptops. They are also going to purchase another company, ABC, that has SAP infrastructure using Oracle Database as the backend (XYZ uses DB2) <--What is DB2?
What are the changes and and considerations that will have to be made to to their client/server infrastructure (a diagram could help)?
How will testing be conducted prior to the companys' systems being merged?
