I am installing a new warehouse. I will be running two instances on the same physical server. I plan to load data into one instance while the other is being used for reporting. At the completion of the load process, I need to point the new user connections to the just loaded instance and allow the old user connections in the reporting database to finish their reports. I need to do this without requiring the a change on either the user desktop or on the application tier (business objects) server. I'm looking for suggestions/ideas on how to best accomplish the task.
