PMP 8.0 Upgrade & License Version

PMP 8.0 Upgrade & License Version

We're currently running version 7600 and looking to upgrade to 8001 but seeing that licensing has changed in this new version I want to verify something. If we are currently running a old premium license will we lose features that we bought before by upgrading to 8001 where now those feature are part of the enterprise license? Are we grandfathered in license wise or will we have to purchase a new enterprise license to continue to use those features?

Thanks!
