Upgrading from 7.0.1 to 8.0 Splunk web stopped running

Hi, I copied /etc from a production running 7.0.1 to a dev. server, changed all named to match the new server, then upgraded to 8.0. Splunk web not running as shown here. The website is not accessible. Hope someone can give me an idea how to fix it. Thank you, [splunk@spkmsaplv001 bin]$ ./splunk restart Stopping splunkd... Shutting down.
