Option 1:
Deploy your application to two different locations. Use the connection string to the old data in one location. Use the connection string to the new data in the other location. Users can then go to the appropriate location and look up information.
Option 2:
Merge the data from both database into a single database. I'm not sure what your structure looks like, so this may not be feasible.
Option 3:
Start coding and make your application use both connection strings. One for when users want the new data and the other for when they want the old.
