Hallo
will update this here regarding my last question.
Jonas didn’t come back before I updated and that impacted my upgrade.
Not Jonas’s Problem. I forgot the question.
Upon upgrading YES you have to USE java 11.
This step is not including in the upgrade steps or in the prerequsites
I had to install openjdk java 11.
After I stoped nexus and moved the backup files
Then using update-alternatives --config java I had to choose the choice for java 11
Only then did I run the "java xxx nexus db migrator xxx " command
Then when i attempted to restart it failed
TWO reasons… I copied the db file to location but I needed to the nexus user ownership
AND I needed to run update-alternatives again and return to java 8
Then nexus worked again
But I needed to check if the effort worked.
Only way is to confirm that nexus.orient.enabled was now false
I can now continue with the upgrade next week.
Please nexus people ! Upgrade your documentation Step
Thank you
Julian
