Upgrade JetBrains YouTrack
It is strongly recommended to create a backup before starting the update process. If you have important data, create and restore a backup to ensure that everything works properly.
To upgrade the application only without modifying any other stack components, stop the servers and follow these instructions.
NOTE: The current JAR file is located at installdir/apps/youtrack/youtrack.jar. You will need to place the new JAR file in the same location.
