I am trying to upgrade from Sonatype Nexus OSS 2.14.15 to Nexus 3.20. According to the instructions at upgrade from 2 to 3 there should be an ‘Upgrade:Agent’ capability in version 2 that I can enable and get a token for version 3. However, there is no such capability to add. There are just ~10 capabilities in the ‘Create new capability’ list’ and none are for upgrading.
I’m not finding any clues as to how to install or enable the upgrade capability. Any tips appreciated!
