License reactivation issue on BIG-IQ DCD Node.

I did query on F5 license server and i the following reply

# Service and Warranty Information

#-------------------------------------------------------------------

Looks like my active support contract already expired. But the license is forever. 

In this doc i read https://my.f5.com/manage/s/article/K93101019#link_01

"A system with an active support contract is considered entitled until such time as the contract expires.  When a support contract expires, the system is not entitled to support until the contact is renewed

Major software upgrades are only supported for entitled systems and require relicensing the BIG-IP system. Minor upgrades do not require relicensing."

My question is do i need to renew support contract to upgrade from 8.1.0 to 8.3.0? Is this minor or major upgrade?
