Upgrading from Nexus 3.x to the latest Nexus 3.x version available

Procedure

Download the latest Nexus 3.x version available from https://help.sonatype.com/repomanager3/download.
Talend Artifact Repository is based on Nexus Repository Manager OSS.
Unzip the new Nexus 3.x installation archive.
Stop and backup the existing Nexus 3.x instance.
In the <NewNexusInstallationDirectory>/nexus-3.x.x-x/bin/nexus.vmoptions file of the new Nexus 3.x instance, update the configuration of karaf.data and Djava.io.tmpdir to the existing Nexus 3.x instance.
Start the new Nexus 3.x instance. It will perform the upgrade automatically during startup. If you installed nexus as a service, you need to change the service setting as needed.
