Warning
The Nexus Migration plugin archive contains a copy of conf/jetty.xml. If you have customized jetty.xml you will want to make a backup of your customized jetty.xml before you install this Migration plugin. Most people using the Nexus Migration plugin are going to be setting up a new instance of Nexus so this shouldn’t be an issue.
Once the Nexus Migration plugin has been installed, start up Nexus and go to the Nexus URL. If you are just setting up Nexus, and you’ve skipped the installation chapter, the default Nexus URL is http://localhost:8081/nexus and the default administrative username/password combination is "admin" and "admin123". If the Nexus Migration Plugin is installed properly, you should see the Artifactory Import link under Administration in the Nexus application menu as shown in Figure A.2, “Artifactory Import Panel from the Nexus Migration Plugin”.
