I have Product prompt and i want to convert prompt values as check box's i.e. if i click on the prompt drill down it as to show the check box's for the prompt values and if i want to select the value or values i want to enable the check box's.
Sounds to me that you're talking about a Multi-Select Prompt. It's possible in a Choice List type prompt when you go to Options on the Prompt dialog, check the box in front of Enable user to select multiple values and you should see check boxes in front of all prompt values.
I did migrated the complete application to production server and dev server.
We didn't had any issue during migration.
