After upgrading from 6.16 to the freshest (7.2.1) I get 404 when trying to access the UI in browser.
In derby.log I see the following:

This error should not prevent Artifactory from starting. 404 after migration to Artifactory 7 usually means you didn't change your reverse proxy config from 8081 (on which Artifactory ran on version 6) to 8082 (the new port for Artifactory in version 7).
While the embedded Tomcat redirects directly, if you use a reverse proxy, such as Nginx, you have to update the redirection rules manually, as described here.
