This will probably a very stupid question to some, but I really need some guidance.
I have a production environment in which there is an unmanaged solution.
We planned the app in the solution in phases. Phase 1 is done, the app is launched, and the users are using it.
Now I have to start on phase 2. Surely I don't want to do this in a production environment. So I created a sandbox environment and copied the production environment to it.
If I now work and make changes in the sandbox, how do I get those changes into the production environment without affecting the data already there? Surely I can't copy the sandbox over to production; that doesn't sound logic at all.
Do I export the solution and import it into production? What happens to the data sitting in production then?
How do you handle ongoing development?
