Free upgrade to Flash Builder 4.7 Would had to shut?

Currently, myself, have a Flash Builder 4.6 CD.

If you are have been completed, please tell me how to upgrade.

For example, such as it is necessary to purchase an upgrade package?

And, the use of the upgrade package to 4.7, possible from 4.6?
