I get my upgrade URL and am able to successfully start the upgrade however after that I get into a failure loop where it cant start.
[Upsource Error] [2018-08-08 16:44:14,909] ERROR - bundle.startup - Error while starting JetBrains Upsource 2018.1: Service hub was started successfully, but shut down process has been initiated
Unfortunately it's the only error I see in the log with exception to this one that happens first:
[Upsource Error] ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. Set system property 'org.apache.logging.log4j.simplelog.StatusLogger.level' to TRACE to show Log4j2 internal initialization logging.
