Do I need a new license for upgrade?
Any time that you perform an upgrade where the first or second digit in the version number changes, you will need new licensing. If you are performing a minor revision upgrade (only the 3rd or last digit changes) then you can continue using your existing license file.
8.3.1 -> 9.2.1 New license file is needed, contact licensing
9.2.0 -> 9.2.1 New license is NOT required as this is minor revision change
9.1.1 -> 9.2.1 New license is requred.
