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'
I'm not finding any clues as to how to install or enable the upgrade capability. Any tips appreciated!
The upgrade agent code only ships in the jetty bundled binaries, the war version of Nexus Repo doesn't have it.
