Returning a license means that the installed license will removed from the machine it is installed on and be placed back onto your account as an entitlement. You will then be able to re-redeem the entitlement onto a different machine or the same machine.

Some reasons for customers to return their licenses back to SideFX:

1. License Type upgrades
2. Product Type upgrades
3. Moving the licenses onto a different license server
4. Converting a license mask to match specific subnets (eg. 192.168.5. * , 10.0. * . *)

Note: When you return your licenses back to SideFX, the licenses still stay on your account unless they are being exchanged or converted, at which point, you will be issued a new set. Returned licenses remain on your account as a holding place until you are ready to re-install.

There is a limit of 3 returns.
