Upgrades modify the version on an existing license, and extensions modify the expiry date. They are used for Indie, Education, and Commercial rentals or Commercial licenses on the annual upgrade plan (AUP).

Sometimes the upgrades or extensions do not get written properly to the locally installed licenses file. You can copy & paste the UPGRADE or EXTEND keystrings for your licenses and manually install them using the License Administrator. This can be found on your account at www.sidefx.com under Services->License Manager->Manage Your License. Click on the License ID.

If you have any questions about a license that should have been upgraded or extended and has not, please contact your account manager or support@sidefx.com.
