Hello, I am looking to upgrade our ancient Nexus version 2.14.18-01(latest 2.x) to the latest 3.x version. After reading this link https://help.sonatype.com/repomanager3/installation/upgrading-from-nexus-repository-manager-2/upgrade-procedures , I am a bit confused. Does the upgrade process require 2 servers to complete( Existing Nexus server2.x and new Nexus 3.x)? Or do I need to deploy on same server and change the port for Nexus version 3?
Thanks in advance
