Updating Plex Media Server Plugin from FreeNAS 11.2-RELEASE to 11.3-RELEASE

 Plex failed to update when I upgrade FreeNAS from 11.2-RELEASE to 11.3-RELEASE. After some Web searches, I found the solution given in this post worked. For convenience, I copied the solution to this post in the following,

1. Stop the plex jail
2. Log on to a FreeNAS shell, and renamed the jail
   

   
       iocage rename plex plexmediaserver
       

3. From the FreeNAS shell, go into /mnt/__YOUR_STORAGE__/iocage/jails/plexmediaserver/ and renam plex.json to plexmediaserver.json,
   

   
       mv plex.json plexmediaserver.json
       

4. Open config.json in the same directory and change the plugin name from plex to plexmediaserver
5. Start the jail again. Everything still worked and both jail and plugin now displayed as plexmediaserver
6. Run the following command to upgrade the jail and the plex plugin
   

   
       iocage upgrade plexmediaserver -r 11.3-RELEASE
