1. My map project needed an update this month and when i referred gmap i saw the notification requesting to migrate to version3. This is from may 19th 2010.
2. There are three projects live which used gmap extensively.
3. Those projects are for Transportation department in which we have plotted a route for a bus service with many options.
4. **What will be the problem if i let the existing projects be as they were. that is in version 2.**

I would like to have suggestions for the above.
