Migration versus upgrade decision chart

The following chart provides a general framework around deciding whether to migrate or upgrade. Not all factors that drive this decision can be anticipated; therefore, a particular environment and its specific requirements may necessitate some deviation in the decision process.

Answer each question below with either Yes or No. Do not answer with both Yes and No. In general, the Upgrade or Migrate column with the most Yes answers is the best choice, assuming there are no “show stopper” items that are not answered in the respective column.
