you can register the 8.2 version as a remote server , it will help you to deploy the application on 8.2 . (it is official way)
there is another way , i did not
test it at all,
you can replace installation folders , i mean you can install the sun apps 8.2 in the same place the 8.1 (bundled with S S C) and create a domain named creator with the same password and user name that creator use.
this way you can use 8.2 for development purpose.
